IRAM Annual Report 2010

The Institut de Radioastronomie Millimétrique (IRAM) is a multi-national scientific institute covering all aspects of radio astronomy at millimeter wavelengths: the operation of two high-altitude observatories – a 30-meter diameter telescope on Pico Veleta in the Sierra Nevada (southern Spain), and an interferometer of six 15 meter diameter telescopes on the Plateau de Bure in the French Alps – the development of telescopes and instrumentation, radio astronomical observations and their interpretation.

IRAM was founded in 1979 by two national research organizations: the CNRS and the Max-Planck-Gesellschaft – the Spanish Instituto Geográfico Nacional, initially an associate member, became a full member in 1990.

The technical and scientific staff of IRAM develops instrumentation and software for the specific needs of millimeter radioastronomy and for the benefit of the astronomical community. IRAM’s laboratories also supply devices to several European partners, including for the ALMA project.

IRAM’s scientists conduct forefront research in several domains of astrophysics, from nearby star-forming regions to objects at cosmological distances.

5Annual report 2010

In the year 2010, both IRAM facilities underwent major enhancements. At the Plateau de Bure inter fer ometer, the refurbishment of all antennas with new precision-machined aluminum panels was successfully completed. Today the array is composed of six antennas with excellent surface accuracies of order 40 microns that enable obser-va tion with maximum efficiency at the highest available frequencies. This refurbishment is also key in preparing the interferometer for the NOEMA project (the greater stability of the aluminum panels diminishing the maintenance time). With their continuous support for this refurbishment, the IRAM Partners have allowed to maintain the observatory at a word-leading level and ensure the long-term future of the interferometer. Another important change that occurred in 2010 was the upgrade of the LO reference system from DRO to YIG-based oscillators, which has significantly improved the phase noise. Finally, all the antennas were equipped with 345 GHz receivers that include electronically tunable 1st Local Oscillators and modified versions of the 2SB mixers developed for the ALMA Band 7, providing excellent noise performance and a 4 GHz IF bandwidth for each polarization. First results obtained using these new receivers have demonstrated the potential of the Plateau de Bure interferometer at high frequencies, yielding cutting-edge scientific results, including the highest angular resolution observation (0.2”) yet achieved at Bure. Some of these results are described in this report.

At the 30-meter telescope, new Fourier Transform spectrometers were installed at the end of 2010 and upgrades are planned for a 32 GHz instantaneous bandwidth. In the laboratory further progress has been achieved in broadband receiver technology with a recent spectacular development of a sideband-separating mixer for the EMIR Band 3 that will extend the frequency range (200-280 GHz) and double the continuum sensitivity. This will lead the way to increased sensitivities, observing speed and flexibility, and consolidate the leading role of the 30-meter telescope for wideband spectral millimeter surveys and studies. During the summer of 2010, a prototype HEMT receiver operating at 3 mm was successfully tested at the 30-meter telescope, showing very good performance in both noise and stability, and this receiver will serve as a test platform for ongoing HEMT amplifier developments.

A major, high-risk action was undertaken in September 2010 at the 30-meter telescope with the installation of two new gearboxes (Azimuth and Elevation) to replace the old ones that showed excessive vibrations and clear signs of ageing. After careful inspection, it was decided to replace the four remaining gearboxes as well. This action will guarantee that the 30-meter telescope will continue to operate in an optimum way and remain the best possible single-dish telescope for millimeter observations.

Continuing the trends seen in recent years, the number of proposals that are submitted continues to increase both at the 30-meter telescope and the Plateau de Bure interferometer. The number of proposals originating from countries outside of the IRAM Partner’s countries remains at a level of about 30% of the observing time. This continuous increase in proposals is translated in the large number of papers that are published based on or using IRAM data, that amount in 2010 to about 150 in total. It should be noted that the total number of papers that includes IRAM personnel is exceptionally high in 2010 as a large number of papers are based on data obtained with the Herschel satellite, a project in which IRAM has been involved at various levels. As in previous years, the topics cover the entire field of modern astronomy, spanning the range from solar system studies to observations of the first objects that were formed in the universe, from the search of new complex or rare molecules to understanding the processes of star formation, from constraining the properties of the gas and dust in proto-planetary disks to detailed studies of the molecular gas in nearby galaxies. The availability of new instruments, the increase in the characteristics of the back-ends and the front-ends and the refurbishments at both facilities each time have opened up new possibilities to study sources that are fainter, probe more efficiently than before the chemical complexity of celestial objects or increase the speed by which studies can be done therefore enabling large scale and more ambitious programs to be conducted.

Examples of scientific highlights are described in this annual report, and include, for instance, the highest angular resolution map yet obtained at the Plateau de Bure interferometer of a nearby proto-planetary disk, the detection of an emission line of water vapor

Introduction


in a high-redshift, strongly lensed source that was uncovered in the H-ATLAS deep survey of Herschel. Another outstanding example is the detection of a new type of instability in the interstellar medium that is the result of the interaction of massive stars with the surrounding molecular gas.

Further enhancements are planned at both IRAM tele scopes and all the technical groups have continued their active work to increase the performances of the facilities and develop new instruments. In particular, the developments for a future heterodyne array receiver for the 30-meter telescope are actively pursued and the design of a 5x5 multibeam receiver for the 3 mm band is in good progress. The backend group is studying a new generation (the 5th) correlator, including pioneering work on multi-bit 8 GHz samplers that will eventually lead to a flexible correlator as foreseen for NOEMA. In view of replacing the MAMBO bolometer camera at the 30-meter telescope, further successful observing tests were done with two bolometer cameras. One, NIKA, is based on Kinetic Inductance Detectors (KID) and build by a consortium of institutes led by the Institut Néel (Grenoble) with a strong implication of IRAM. The recent observing tests provided further very encouraging results in both of the 2 and 1 mm windows. Further improve-ments will be made and new observations are planned in the course of 2011. Another bolometer camera, GISMO, based on TES technology and build by the Goddard group at NASA, operates in the 2mm window. This camera was recently tested again at the 30-meter telescope with results that are

so encouraging and stable that it could be made available to the community for general use. These successful observing tests provide a useful basis for the building of a new generation large field of view bolometer camera for the 30-meter telescope.

Concerning the ALMA Band 7 production, its pace is fully sustained. A milestone was reached at the end of 2010 when half of the 65 (and 8 spares) receivers, with state-of-the-art performances, were delivered to and accepted by the ALMA project. The production during the year 2010 amounted to nineteen receivers. The project should normally come to completion at the end of 2012.

Planning the future of IRAM, the activity around the NOEMA project gained further momentum during 2010. In July 2010, an international Visiting Committee, chaired by Robert Wilson (Center for Astrophysics), reviewed the activities of IRAM and gave strong support for the NOEMA project. The report of the Visiting Committee provided the basis for detailed discussions at the Partners’ level to explore how to best implement and build the NOEMA project in a timely fashion. The Partners agreed to make the necessary resources available to start the project in a Phase 1 that will include the construction of a set of 4 antennas with receivers and a new correlator.

The year 2010 was again a remarkable year with many major achievements at both IRAM facilities: projects were successfully completed, while others were started or are under development; many out-standing scientific results that are based on IRAM data have been published, including large and ambitious observing programs that have a high impact and visibility; the ongoing improvements that occur at all levels to keep the instrumentation up to date and plan for the future, gradually trans-form the IRAM observatories into more efficient, versatile and outstanding facilities; last but not least, the positive decisions which were made by the IRAM Partners to expand the Plateau de Bure interferometer and transform it, in the next coming years, into the Northern Extended Millimeter Array, will have a profound and positive impact on the future of IRAM and its role in the ALMA era.

Highlights of research with the IRAM telescopes in 2010

HerscHel Gravitational lenses: iraM follow-up studies

Gravitational lensed sources have played an important role in infrared and sub-millimetre studies of high-redshift galaxies and active galactic nuclei (AGN) since the discovery of FSC10214+4724 by the IRAS satellite (Rowan-Robinson et al. 1991). Similar sources (including the Cloverleaf ) triggered the sub-millimetre studies of galaxies in the early universe and allowed pioneering detections of the properties of these systems through observations of the emission of the dust continuum and the molecular lines. In this new field, the IRAM facilities played a key role from the early 1990’s onward. The results demonstrated the usefulness of strong gravitational magnification in the investigation of the detailed properties of distant galaxies.

This observational field has recently received a new boost from the results released from the wide-field surveys done with the Herschel Space Observatory – in particular, the H-ATLAS and HerMES projects that will cover 570 and 70 square-degrees, respectively (Eales et al. 2010; Oliver et al. 2010). These surveys have already increased the area of sub-millimetre surveys by factors of hundreds compared to the widest surveys that were previously available. One may expect that the number of strongly lensed sources will be multiplied by a similarly large factor. This expectation is confirmed by the first analysis and study of the strongest sources, which were uncovered so far in H-ATLAS, and were shown to be at high redshifts, i.e. 1.5<z<3 (Negrello et al. 2010). This result triggered a wealth of follow-up observations at all wavelengths to further

characterize the nature of these high-z sources as well as the properties of the lensing galaxies.

Prominent amongst these observations are those done at sub/millimetre wavelengths. The strength of the sources detected by Herschel together with recent technological developments at the sub-millimetre facilities has opened a new area. In particular, the redshift of these sources, which are enshrouded in dust, can now directly be determined from the measurement of a series of CO lines. To date the distances to more than 10 sources uncovered in the Herschel deep-field surveys have been measured using this technique, at the CSO and now APEX (with ZSpec), the GBT (with Zspectrometer), CARMA and the Plateau de Bure interferometer (with the newly installed correlator, WideX). As an example, the redshift of the most prominent, highest redshift source found so far (ID.141) was ‘blindly’ determined at the Plateau de Bure interferometer, yielding a redshift z=4.24 (Cox et al. 2011). The detection of CO lines using the Plateau de Bure interferometer enabled robust redshift determination of five other Herschel lensed sources in the redshift range 2<z<3 (Negrello et al. 2010; Riechers et al. 2011). The determination of the redshift allows further searches to be performed, especially of weaker lines, to probe the physical conditions and the chemistry of the molecular gas in these systems.

A recent example of a follow-up study is that of the lensed sub-millimetre galaxy LHSW-01 at z=2.957, one of the strongest HerMES sources found so far, which was mapped in the 5-4 transition of CO using the Plateau de Bure interferometer. The observations spatially resolve the molecular gas and the dust continuum emissions into four lensed images with


a maximum separation of 9”, revealing the internal gas dynamics in this system.

Another example is the detection of water in the 2

ID.17b (z=2.3052), using the band 4 receiver at the Plateau de Bure interferometer (Omont et al. 2011) - confirming a previous, tentative detection done at the CSO (Lupu et al. 2011). The intrinsic water line luminosity in ID.17b is comparable to that of the local ultra-luminous starburst galaxy Mrk231 and the excitation of the H₂O levels are probably similar in both objects. This detection shows that some of the Herschel lenses can harbour a rich chemistry that remains to be studied in the future with ALMA and NOEMA.

The examples of these recent studies provide us with a first glimpse of what can be expected in the future from this unique sample of hundreds of Herschel high-z lensed galaxies: today with Plateau de Bure, soon in the frame of the ALMA Early Science, and later with the fully operational ALMA and NOEMA. The enhanced capabilities of the latter facilities will allow countless extensions for each of the topics mentioned above, including: blind CO redshift determination and search for objects at the highest redshifts; high-resolution imaging and dynamics of strongly lensed galaxies; comprehensive studies of dark matter in high-z deflectors; high sensitivity molecular (and atomic) spectroscopy; molecular gas in high-z Active Galactic Nuclei; search and study of exceptional, high-z lensed systems: highest

magnifications; double object lensing by the same deflector; radio-loud sources; or high-z masers.

MM18423+5938: an extreMely BriGHt Galaxy in tHe early universe

In the course of a program designed to search for debris left by the formation of planets around nearby stars, Lestrade and collaborators serendipitously discovered an extremely bright source, using MAMBO at the 30-meter telescope. Subsequent follow-up spectroscopic observations showed that the source MM18423+5938 was a galaxy at a redshift of z=3.93 undergoing vigorous, dust-enshrouded star formation activity. Bright, star-forming submillimeter galaxies (SMGs) trace the most massive galaxies assembled during an active phase of galaxy formation, which peaked at a redshift around ~2.5. Their star formation rate can be prodigious (up to 1000 M per year) and the underlying starburst activity is believed to result from major merger events.

The apparent infrared luminosity of MM18423+5938 is estimated to be 4.8 1014 L and the inferred apparent star formation rate is 8.3 104 M per year, about 50 times higher than for the most prolific star-forming galaxies known. The molecular hydrogen gas (H2) fueling star formation was estimated to be between 2.1011 and 11.1011 M, which is at least as large as in the most massive galaxies known but which are older and have had more time to build up their masses. All these values clearly point to gravitational amplification.

To measure the redshift of MM18423+5938, Lestrade et al. used EMIR, the multi-band heterodyne receiver installed in 2010 at the 30-meter telescope. Its 7.4 GHz wide, dual linear polarization bandwidth was used to search for emission lines of carbon monoxide. Several lines were detected which enabled a robust determination of the redshift of this source. The 12CO line excitation was found to be moderate, suggesting that there is no strong heating by a central AGN and that the starburst activity must be moderate.

The galaxy MM18423+5938 must be amplified by a intervening massive and closely aligned foreground galaxy. High angular resolution observations using interferometers at millimeter and radio wavelengths, which should reveal the multiple mirror images of MM18423+5938, are currently underway. These observations will help to constrain the lensing and to study at high resolution the morphology and

the properties of the molecular gas where the star formation activity takes place. These data will also be useful to further understand how galaxies built up their masses and assembled their stellar populations early in cosmic time.

Quasar feedBack disclosed By Giant Molecular outflows

In the standard scenario for galaxy evolution, young star-forming galaxies transform into red bulge-dominated spheroids, where star formation has been quenched. To explain this transformation, a strong negative feedback generated by accretion onto a central super-massive black hole is often invoked. The depletion of gas resulting from quasar-driven outflows should eventually stop star-formation across the host galaxy and lead the black hole to “suicide” by starvation. Direct observational evidence for a major quasar feedback onto the host galaxy is still missing, because outflows previously observed in quasars are generally associated with the ionized component of the gas, which only accounts for a minor fraction of the total gas content, and typically occurs in the central, compact regions (on ~pc scales).

To investigate whether the fast outflows observed in the nearby active galactic nucleus (AGN) Mrk231 in the atomic gas phase are also affecting the molecular gas phase, Feruglio and collaborators used the Plateau de Bure interferometer to perform a deep integration in the ¹²CO(1-0) emission line. Thanks to the correlator WideX, they succeeded in detecting the low surface-brightness wings of the line, with velocities of up to 750 km/s that are spatially resolved on a 1kpc scale. Despite several previous observations of CO in Mrk231, these wings were never detected before, on one hand because of insufficient frequency band coverage, on the other because of the intrinsic low surface brightness of the wings (the flux of the broad component is ~1/5 flux of the narrow core). Feruglio et al. suggest that the broad wings trace a giant molecular outflow of about 700 M /yr, about 3-4 times larger than the ongoing star-formation rate observed in the host galaxy.

The authors expect that the wind will expel the cold gas reservoir in about 10⁷ yr and halt the star-formation activity on the same timescale. The inferred kinetic energy in the molecular outflow is ~10⁴⁴ erg/s, corresponding to a few percent of the AGN bolometric luminosity, which is very close to the fraction expected by models ascribing quasar

feedback to highly supersonic shocks generated by radiatively accelerated nuclear winds. In contrast, the contribution by supernovae associated with the starburst fall short by several orders of magnitude to account for the kinetic energy observed in the outflow. The direct observational evidence for quasar feedback provides solid support to the scenarios ascribing the observed properties of local massive galaxies to quasar-induced large-scale winds.

cold Molecular Gas in tHe inner two kiloparsecs of nGc 4151

NGC4151 is one the best studied nearby active galaxies and is sometimes referred to as the proto-typical Seyfert 1. Although it has been extensively observed at all wavelengths and on various spatial scales, information was still missing on the cold gas in between the leading side of the large scale stellar bar (at about 1 kpc from the nucleus) and the putative torus observed in HI absorption on parsec scales.

Using the Plateau de Bure interferometer, Dumas and collaborators obtained the first spatially resolved spectroscopic imaging observations of the ¹²CO(1-0) line emission in the central 2.5kpc of NGC4151. The 3mm continuum emission was found to arise from the location of the active nucleus with a flux of 14mJy and appears to be unresolved at an angular scale of about 2.8” (or 180pc). The total cold molecular gas mass detected is 2,107 Msun. Most of the CO is distributed along two curved features, about 1 kpc north and south of the active nucleus and coincident with the circum-nuclear dust ring. The gas kinematics within these arcs is consistent with motions due to the large-scale stellar bar, derived from neutral hydrogen observations. Two

additional CO clumps showing non-circular motions are detected: one associated with the southern feature and the other lying at about 600pc north of the nucleus. Finally, and very surprisingly, no cold molecular gas is detected in the central 300pc, where abundant near-infrared H₂ line emission is present. This suggests that either the H₂ line emission is not a good indicator of cold gas in NGC4151, or that the relatively low column density in this X-ray dominated region leads to a low CO abundance relative to H₂. The upper limit of the cold molecular gas mass from the CO line in the central 300pc is 10⁵ M, which is sufficient to support the AGN activity at its current levels for 10⁷ yrs, the typical lifetime of nuclear activity.

cold Gass - an iraM leGacy dataBase for tHe Gass survey

One of the most fascinating aspects of galaxies in the local universe is the complex system of cor re la-tions between their global physical properties. These correlations form the basis of the so-called scaling laws, which are important because they provide quantitative means to understand the physics of galaxies, their formation and their evolutionary his-tory. Scaling laws have been proposed for a variety of properties and systems, but only very few exist that describe how the global cold gas properties correlate with other global physical properties of galaxies. To shed new light on how the cold gas, atomic gas and stars relate to each other, Kauffmann and Kramer initiated with their collaborators the COLD GASS observational project.

COLD GASS is an international collaboration and an ongoing 30-meter telescope Legacy Survey using EMIR, that is aimed at measuring the amount of cold gas through the ¹²CO J=1-0 emission line in a statistically representative sample of massive (M*>10¹⁰ M) galaxies in the local Universe (0.025<z<0.05). The sample, which covers a wide range of Hubble types from star-forming spirals to red-and-dead ellipticals and two orders of mag-ni tude in luminosity (0.1-10 L*), was designed to establish an unbiased reference multi-wavelength database from radio to near UV of 350 galaxies within the area of overlap of the SDSS spectroscopic survey, the ALFALFA survey, and the GALEX Medium Imaging Survey.

The figure shown herewith displays first results of the survey. The left-hand panel shows the relation between the molecular gas fraction M(H₂)/M* and the NUV-r color of a sample of 222 galaxies. It appears that the empirical threshold of NUV-r=5

marks an abrupt transition from the active gas-rich star forming galaxy population to a more passive population characterized by molecular gas fractions lower than 0.015.

The date displayed in the right panel indicates that the mean molecular gas depletion time scale increases by a factor of 6 across the mass range sampled by the NUV-r<5 galaxies of the COLD GASS survey, and that this variation correlates strongly with specific star formation rate, NUV-r color and stellar mass. Previous surveys were unable to observe this variation because of the limited statistical range of their samples. While it is known that gas depletion times are significantly shorter in starburst galaxies and mergers of the local Universe, the importance of these results is two-fold. First, they produce compelling evidence that the gas depletion timescales also varies within the population of “normal” star-forming galaxies, and, second, these results quantify this variation as a function of a range of fundamental parameters.

a new instaBility revealed in tHe orion Molecular cloud

Massive stars influence their immediate surrounding and have profound impacts on their parental mole-cular clouds, fragmenting, compressing and dis rup-ting them. Hydrodynamical instabilities are thought to play a fundamental role in these processes although identifying them remains difficult. The Orion nebula is the closest-by example of a region forming massive stars (at a distance of 414 pc) and has therefore been a choice laboratory for exploring the influence of massive stars on the surrounding molecular gas. Recently, Berné and collaborators have obtained a new complete map of the Orion nebula in ¹²CO(2-1) using HERA at the 30-meter telescope with a spatial resolution of 12” (0.025 pc) and a spectral resolution of 0.4 km.s-¹.The spatial

coverage and angular resolution of this map allows a comparison of the distribution and the dynamics of the molecular gas with maps at other wavelengths with comparable spatial coverage and resolution as shown in the accompanying figure.

In the southwest region of the nebula, Berné et al. reported the presence of a series of regular waves (ripples) enshrouding an elongated molecular cloud and displaying strong velocity gradients. This structure follows closely (with clear stratifications) similar features that are traced in H₂ and in the emis sion features of very small grains (PAHs). From a careful analysis of the relative distribution of these various tracers, the authors conclude that this remarkable periodic structure and its velocity field are consistent with hydrodynamical instabilities that result from the interaction of high-velocity plasma/gas, produced by massive stars, with the dense mole cular gas. The characteristics of the structure are consistent with a Kelvin-Helmholtz instability that arises during the expansion of the nebula as gas heated and ionized by massive stars is blown over pre-existing molecular gas.

fraGMentation and Mass seGreGation in cyGnus x

Massive dense cores (MDCs) are the high-mass equivalent of the so-called dense cores in nearby star-forming regions. With typical sizes of 0.1 pc, they could form either a few high-mass stars, or a cluster of low-mass stars. To constrain the result of the fragmentation process in regions that offer the opportunity to reach scales at which individual collapsing objects can be separated, Bontemps and collaborators observed the six most massive and youngest dense cores in the Cygnus X complex using the Plateau de Bure Interferometer at 1.3 and 3.5 mm.

From Saintonge et al. 2011, MNRAS, 415, 32 & 61


With the exception of the most compact MDC (CygX-N40), which harbors a single protostellar object of ~60 M, the remaining MDCs seem to have collapsed into a number of compact fragments with sizes and separations similar to low-mass pre-stellar condensations and Class 0 young stellar objects in nearby proto-clusters. The level of fragmentation is found to be higher than in the turbulence regulated monolithic collapse scenario but not as high as expected in a pure gravo-turbulent scenario where the distribution of mass is dominated by low-mass (proto)stars. The high fractions of mass

in the protostellar fragments are also indicative of an enhanced efficiency of core formation in the MDC. The increase in the core formation efficiency as a function of average density in the MDCs is suggested to be due to the increasing importance of self-gravity that leads to gravitational collapse on the scale of the MDCs. At the same time, the observed MDCs tend to fragment into a few proto-stellar objects within their central regions. Bontemps et al. conclude that we are probably witnessing the primordial mass segregation of clusters.

tHe protoplanetary disk around tHe younG star lkca15

Hundreds of exoplanets have been discovered around nearby main-sequence stars. A massive effort is underway to find more planets, determine their key properties, and explain demographic trends with models of their formation. But asso-ciating the current exoplanet properties with their formation epoch can be problematic, since the formation process is intimately associated with the initial conditions in the progenitor circumstellar disk. Ideally, the properties of mature exoplanet systems could be compared with those for their younger counterparts that are “caught in the act” of formation, still embedded in their natal disks. The results would refine our understanding of planet formation timescales and help characterize how exoplanet

properties are shaped by early interactions with disk material.

While the direct detection of a planet orbiting a young star is currently a challenge, the presence of a giant planet can be inferred indirectly through its dynamical influence on the structure of the remnant disk material. A sufficiently massive planetary companion can open a gap that impedes the inward flow of mass through the disk, quickly producing a low-density cavity at the disk center. The size of the cavity is set by the planet orbit, and the amount of material inside it depends in some way on the planet mass. Therefore, observational constraints on the sizes and mass contents of these disk cavities can offer some initial insights into the orbital architectures and masses, respectively, of planetary systems at ages of only ~1 Myr. The best way to measure such disk structures is with high-quality, sensitive, and high angular resolution observations of the millimeter dust continuum emission.

Using the new band 4 receivers and the WideX correlator in the A configuration, the Plateau de Bure interferometer has recently resolved the large cavity (R = 50 AU) in the proto-planetary disk around the young star LkCa15 at a continuum frequency of 346 GHz. While a detailed modeling effort will be required to interpret the properties and underlying origins of this cavity, these exceptional data represent a first step in the development of a new, indirect method for identifying potential young exoplanet systems through the sub/millimeter imaging of their associated disk structures.

tHe cosas survey of aGB and post-aGB stars

The evolution of transition objects between the asymptotic giant branch (AGB) and the planetary nebula (PN) phase is spectacular, probably the all-decisive moment where very efficient mass loss processes determine the basic morphological, dynamical and chemical layout of the future PN. While these processes are not well understood, radiation pressure on dust grains in the cool and dense circumstellar shells and atmospheric shock waves driven by inner envelope pulsations are both suspected to be at work. According to present knowledge, the rapid evolution of stars towards the end of the AGB seems to be related to the appearance of high-velocity winds in the innermost regions and a clear breakdown of the spherical symmetry of the circumstellar envelopes. These winds, which are often highly collimated, run into

the dense, dusty layers of the envelope inducing shocks and structural deformation.

In the frame of the COSAS (CO Survey of late AGB Stars) collaboration, Castro-Carrizo and collaborators have mapped and analyzed the ¹²CO J = 1-0 and 2-1 emission lines in a representative sample of circumstellar envelopes around AGB and post-AGB stars. The survey was undertaken with the aim of investigating small and large-scale morphological and kinematical properties of the molecular environ-ment surrounding stars in the late AGB and early post-AGB phases. For this, COSAS combines the high sensitivity and spatial resolving power of the Plateau de Bure interferometer with the better capability of the 30-meter telescope to map extended emission. The global sample encompasses 45 stars selected to span a range in chemical type, variability type, evolutionary state, and initial mass. COSAS provides sensitive means to quantify variations in the mass-loss rates, assess morphological and kinematical features, and investigate the appearance of fast aspherical winds in the early post-AGB phase.

Based on this survey data, the authors conclude that the envelopes around late AGB stars are mostly spherical, often mingled with features such as concentric arcs (R Cas and TX Cam), broken spiral density pattern (TX Cam), molecular patches testifying to aspherical mass-loss (WX Psc, IK Tau, V Cyg, and S Cep), as well as with well-defined axis-symmetric morphologies and kinematical patterns (X Her and RX Boo). The COSAS sources span a wide range of angular sizes, from relatively compact (CRL 2362, OH 104.9+2.4 and CRL 2477) to very large (χ Cyg and TX Cam) envelopes, sometimes partially obscured by self-absorption features, which testify to the emergence of aspherical winds in the inner-most circumstellar regions.

first oBservations of interstellar anion cn-

The discovery of interstellar anions is probably the most remarkable result recently obtained in the field of astrochemistry. After the synthesis and characterization of C₄H-, C

6H-, C

8H- and C

3N- in

the Harvard spectroscopic laboratory and their subsequent identification in the spectrum of IRC+10216, a fifth anion was identified in 2008 in the same source without the help of any laboratory data: C

5N-. Up to now, only the n=1 members of the C

2nH-

and C2n-1

N- series remained unidentified in space, although their transition frequencies are precisely known.

C-chain anions are believed to be formed by electron radiative attachment on neutrals. As predicted by models, the abundances of C

6H- and

C8H- are fairly large and represent a good fraction

(~1/10) of the abundances of their parent neutral species C

6H and C

8H. On the other hand, the

abundances of C4H- and C

3N- relative to C

4H and

C3N are much smaller (≤1/4000). This is explained

by the fact that C4H- and C

3N- are shorter than C

6H-

and C8H- and have less low-lying vibrational states,

making electron attachment less probable. For the very short radicals CN and C

2H, which have only a

few vibrational states, the theory predicts vanishingly small electron attachment rates. The non-detection of CN- and C

2H-, down to very low levels, was

therefore expected. Yet, remarkably, Agundez and collaborators succeeded in detecting 3 lines in the millimeter wave spectrum of IRC+10216 that they could assign to CN-, the shortest of the two anions.

The three lines are shown in the accompanying figure. The first two lines (one appears as a low intensity shoulder of a much stronger C

6H line, the

other as a broad feature blended with a SiC2 line)

were tentatively assigned to the J=1-0 and 2-1 transitions of CN- but only the detection of the J=3-2 transition using EMIR (shown in the upper panel) ultimately led to the clear-cut and unambiguous identification of the anion: its rest frequency, which was found identical to the predicted one, left little doubt on the detection of CN-.

The abundance of CN- derived from the line inten si ties is many orders of magnitude larger than predicted by statistical theory calculations of electron attachment. Although electron attachment rate coefficients are difficult to calculate precisely and are only evaluated through statistical theory, the disagreement seems much too large and suggests another formation route than the attachment of an electron to CN.

ZooMinG in on tHe nucleus of coMet 8p/tuttle

Comets have challenged generations of astronomers, yet much remains to be understood about the properties of their nuclei. Understanding their physical and chemical properties is one of the most challenging issues in the study of planetary formation. They potentially provide crucial details on the initial thermo-physical conditions of the Solar proto-planetary disk and on the subsequent formation of the icy planetesimals from which the cores of the outer planets were formed.

During a recent observing campaign using the Plateau de Bure interferometer, Boissier and collaborators succeeded in observing the thermal continuum emission at millimeter wavelengths from the nucleus of Comet 8P/Tuttle. It was ejected to the outer Solar System and preserved in the Oort cloud until it came back in the inner Solar System as a Halley type comet. Observed at 240 GHz on January 8, 2008, it was detected with a flux density of ~3 mJy. By combining these millimeter measurements with visible and mid-IR data, the authors were able to constrain the surface properties of the ~2.5 km-sized nucleus and derived a thermal inertia ≤10 J/K.m-2.s-1/2 and a millimetric emissivity of ~0.7-0.8. This low emissivity suggests the sub-surface layers of the nucleus do contribute to the detected continuum emission.

Several important events took place at the 30-meter telescope on Pico Valeta, including the installation of the new Fourier transform spectrometers, the replacement of the gearboxes and the successful testing of new bolometer cameras.

As in previous years, the 30-meter telescope is highly demanded by the community with almost 200 projects that were observed during 2010. About an equal number of observers visited the observatory to conduct their own observations or help with other projects during several weeks of pooled observations. The new eight-mixer receiver EMIR, including its new 345 GHz band, is strongly demanded due to its unique sensitivy and bandwidth. A large part of the technical work

described below was focused on preparing for yet larger bandwidths to be covered by fast Fourier transform spectrometers.

During the winter semester 2010/2011, the fast Fourier transform spectrometers (FTS) were offered for the first time for routine observations. The available eight FTS units cover 8 GHz of bandwidth at 195kHz resolution. These units only form the first part of the extension to 24 units, which is planned for autumn 2011. This revised IF system will cover an instantaneous bandwidth of 32GHz. In order to prepare for this major upgrade, we started to revise the entire data handling system of hard- and software (see below).

Since December 1, 2010, the 8 GHz FTS have been successfully used with EMIR in all observing modes. An example of data obtained with this new facility is displayed hereby and demonstrates the power of the new system. It shows frequency surveys near 346 GHz using the WILMA and FTS backends of two Oxygen-rich circumstellar envelopes around evolved stars that both show a wealth of emission lines witnessing the chemical complexity.

Two prototype bolometer cameras were tested at the telescope in 2010. The GISMO 2mm camera has 128 pixels and uses transition edge sensors (TES) and squid amplifiers and multiplexers for readout. In April 2010, the GISMO team, led by Johannes Staguhn (Goddard/USA), tested a much-improved instrument in a 3rd test run at the 30-meter telescope. Remaining problems were identified. With the help

of the CRUSH-2 data reduction package written by A. Kovacs some very promising results were obtained. For example, the starburst galaxy AzTEC-3 at a redshift of z=5.3 was detected with a flux density of 3.7mJy at 2 mm (Capak et al. 2011).

The Neel IRAM KIDs Array (NIKA) camera uses kinetic inductance detectors (KIDs). For the 2nd test run at the 30-meter telescope in October 2010, the instrument had been upgraded to include dual-band optics for simultaneous observations at 150 and 220 GHz using two spatially separated KID arrays. In this version of the instrument, a grid polarizer achieves the band splitting. The arrays comprised 144 pixels at 2mm and 256 pixels at 1mm. A number of faint and extended objects were imaged including SgrB2, Cygnus A, and NGC1068 (Monfardini, Benoit et al. 2011).

astronoMical proJects

During the year 2010, a total of 188 projects were scheduled at the 30-meter telescope. This number includes 3 Large Programs, 14 Director’s time proposals (DDT), and 8 VLBI projects. A large fraction of these projects (74 or 39%) was scheduled in pools. The fraction of projects observed remotely has increased further, to 11% (20 projects).

192 observers visited the observatory during the reporting period. Many of these visitors came two or more times to the telescope. Forty observers came to help with the pool observations, and seven of them actually came for more than one week.

From the proposals eligible for RadioNet support, 27 were scheduled at the telescope and 8 European observers were granted travel support.

Two global 3mm VLBI sessions were carried out during 10 days in 2010. A dedicated test at 1mm between the Pico and the Plateau de Bure showed good quality fringes.

telescope operation

About 60% of the total time in 2010 was used for observations and about 30% of the time was lost due to adverse meteorological conditions. The amount of time lost is much less during summer than during winter, similar as in previous years. About 10% of the time was used for regular maintenance and dedicated technical projects. Less than 0.8% of the time (about 68 hours) was lost due to technical problems. Here, we only count failures of more than 2 hours, which are directly noticed by the staff. However, each important failure is monitored, analyzed and discussed to further improve the system.

Out of the 68 hours, 28 hours in total were lost in the telescope area, 16 hours were lost due to front-end problems, and about 24 hours because of computer related problems.


antenna and electronics

The main effort and activities in the telescope area were related with the daily operation of the observatory: periodically maintaining the systems and equipments for observation, including the pointing model, helping with the daily problems concerning the observation and operation, and repairing broken equipment.

Other activities in the telescope area during 2010 that deserve to be mentioned are:

■■ During two weeks in September 2010, two of the six antenna gearboxes were replaced, one for azimuth and one for elevation, by new gearboxes built by the German company Desch. This exchange became necessary as some of the

old gearboxes exhibited enhanced vibrations indicating wear. In preparation of this exchange, we characterized these vibrations and installed two new electrical cranes to permit moving of up to 3 tons inside the antenna tower. We also installed manual cranes in the roof of the motors room, which had to be reinforced. The gearboxes were characterized by measuring stiffness, transfer function, hysteresis, rolling friction, operation of brakes, etc.. The exchange went very well and smoothly due to a careful preparation. It is planned to replace the remaining 4 gearboxes in 2011 and 2012.

■■ In early 2010, a protective plate of one of the legs was blown off the 30-meter telescope. It was replaced during the summer period. To prevent such problems in the future, the rivets of the back-structure were revised. Several tens of rivets, that showed signs of wear, were replaced.

■■ The telescope sun avoidance system was improved by implementing a mechanism to automatically close the antenna vertex when the distance between the antenna beam and the sun is less than 0.75°, i.e. in case the antenna has accidentally moved into the sun avoidance zone of 1°. This mechanism is independent to what is implemented in the antenna control program ‘AntennaMountDrive’ and works all the time, even when the antenna is stopped. The main goal is to protect the receivers from being saturated.

■■ The antenna Error Beam was measured with Moon observations in collaboration with A. Greve and C. Kramer. New values of the Error Beam improve on the findings of 1998. A report is in preparation.

■■ Measurements were done to characterize the antenna gain elevation curve, telescope efficiencies, and insertion losses of the vertex radome at 340 GHz.

front-ends

The EMIR receiver continues to produce data of exceptional quality and, by now, can be considered to be the core of the 30-meter telescope front-end area. Acquired experience over the past two years show new effects that were not detected during the initial commissioning phase. Some new interferences at fixed frequencies in the IF band were found. Whereas some of these spurious signals are from a known origin (oscillators from other receivers), others are not yet understood and are still under investigation. A mechanical problem on one of the EMIR calibration motors stopped receiver operation during some days. One of the position sensors was found defective, probably due to the very frequent use of the part. The damaged piece was replaced but a longer-term solution needs to be found.

HEMT test receiver at the 30-meter telescope.

The IF system will be upgraded to a total bandwidth of 32 GHz in 2011, doubling the bandwidth available for the backends. To prepare for the strong increase in the total instantaneous bandwidth, a revision of the IF transport and switching scheme has been started. A new equalizer unit, good for 4 new coaxial cables, each transporting 4 GHz of bandwidth, was built. The EMIR receiver will be upgraded further in 2011 by installing 2SB mixers for the E230 and E330 bands.

Some performance degradation was found on one of the HERA Local Oscillator (LO) boxes. The two oscillators were completely refurbished in Grenoble and later installed and commissioned at the telescope.

Tests on experimental bolometer cameras (GISMO and NIKA) were continued over the year. The bolometer prototypes include new upgraded sensors arrays providing a much-improved sensitivity (see above).

Finally, a new dual polarization HEMT test receiver was installed in August 2010. Initial results, after commissioning at the telescope, show very close agreement to measurements made in laboratory conditions in Grenoble. The results are also com-pa rable in performance to the best SIS receivers. Allan variance results demonstrate good receiver stability, even comparable to the specifications for ALMA receivers. This fact, coupled to the extremely large bandwidth (>30 GHz), makes this receiver a good candidate for pointing and other continuum measurements. The prototype receiver will help in solving the question of which technology to use for a future 3 mm multi-beam heterodyne array.

Backends

In autumn 2010, 8 new fast Fourier transform spec tro meters (FTS) from Radiometer Physics (Meckenheim, Germany) were integrated into the system. This FTS will enable observations with EMIR, using the 2x4GHz bandwidth with a resolution of 195 kHz. The FTS units were connected to the 4 MHz processor and installed in parallel to the 4 MHz backend. In preparation, the synchronization signals had to be debugged with help by Bernd Klein at the MPIfR (Bonn, Germany). Data transfer and control were developed and a new 19” rack for the IF processor and three FTS crates were installed in the backend room. Since the start of the winter semester 2010/2011, the FTS units have been successfully offered to the astronomers and first results are displayed above.

In preparation of the new IF system, which will offer 32GHz of instantaneous bandwidth with 24 FTS units, we installed a second distribution box for 4 more IF cables transporting 4GHz each. Work on new broadband continuum detectors continued in 2010. The temperature control, detec-tor boards, data readout, and the FPGA program-ming were developed for commissioning in spring 2011. For the VESPA auto-correlator spectrometer, offset voltage corrections were installed for all samplers to adapt to the increased dynamic range between the cold load and the sky of EMIR.

coMputers

In the computer group, the following activities took place in 2010.

■■ New Server System at the Observatory: The server computers that control the telescope that are used for data-processing (mrt-lx1,..,3) were replaced. The new computers are equipped with faster processors, more cores and more memory. Each computer now has 16 disk slots, which allows installing up to 96 TB of disk space (based on 2TB disks). A fallback hardware (mrt-lx0) is available to replace a broken server. In order to prevent disk failures, all system have a RAID controller installed with hot-swap spare disks.

■■ A tape autoloader that can automatically load one LTO tape from 16 tapes was installed and the LTO-5 tapes that have a capacity of 1.6TB (uncompressed) were switched. The backup sys-tem was changed to use the open-source tool ‘Bacula’.


■■ Moving from 32 to 64 bit systems: During the preparation for the new FTS back-ends, it was realized that the current operating system (32-bit architecture) imposed a severe limit on data reduction. When the hardware of the main telescope control and data reduction computers was updated, it was decided to also change the system architecture to 64-bit. This implied a new operating system. The basic architecture is now 64-bit, but support for programs compiled for 32-bit architecture was also installed.

■■ Telescope Control: Today the telescope control system supports the new FTS backends. The increase in backend channels (approx. 10 times more) requested the replacement of the server systems at the observatory as described above.

■■ The receiver control software was modified to support the HEMT receiver installed in 2010. A new fallback hardware for the MAMBO backend (ABBA) has been installed.

■■ Organization of observing projects: The project organization has been improved. Projects and TAPAS accounts are now created based on the information from the IRAM Scheduler database. The Principal Investigator is informed by e-mail that the project has been created and can be accessed via Internet.

■■ TAPAS database of observations header information: The data-format of the observation header information for the CDS (Centre de Données astronomiques de Strasbourg) has been defined and a first set of data included into the CDS database (2009-10/12).

control systeM (ncs)

The main effort in the development of the NCS in 2010 was the support of the new FTS backend. This includes the beginning of a major revision of the logistics of the data handling and processing because of the much larger data rates.

More technical time than usual was lost to bad weather, creating a bottleneck in NCS testing, particularly toward the end of 2010 – without harming the observations except that we needed to schedule some additional Technical Time in December. Moreover, several developments started in 2010, remained unfinished.

Further improvements were made of the safeguards for the experimental observing modes for GISMO, i.e. Lissajous curves, which use the tracking capabilities

of the 30-meter telescope to its limits. These improvements are now also active for standard observations, including the execution of scans and alarms for tracking problems, with simple default values, though some fine-tuning remains to be done.

Unification in the NCS software development was achieved allowing the observer to use the same revision of paKo and the same version of the antenna mount drive software for routine observations using the heterodyne receivers, MAMBO, and GISMO.

Before and after the gearbox exchange, all the tracking and observing modes were extensively tested to assure the tracking quality.

At the less “visible” levels, improvements were made in the limits for the EMIR frequencies, in several alarm and warning messages, antenna tracking, secondary (“spindles”) control, sun avoidance, support for experimental instruments, e.g., the HEMT receiver and the NIKA bolometer, and other aspects of the NCS.

Miscellaneous

In April 2010, Breezy Ocana, finished her PhD thesis on “The interstellar medium in nearby elliptical radio galaxies” and successfully defended it at the Universidad de Granada. Jorge Abreu Vicente, who graduated at the Universidad de La Laguna on Tenerife, joined the team of astronomers in Granada in August, and became a new Astronomer of Duty and PhD student. End of July, Helmut Wiesemeyer left IRAM for a sabbatical year in the group of Karl Menten at the MPIfR (Bonn, Germany). Albrecht Sievers has taken over Helmut Wiesemeyer’s work of maintaining and developing the calibration package MIRA and the online data processing (odp), and preparing for the new high resolution Fast Fourier Transform Spectrometers.

As in previous years, IRAM offered guided tours through the observatory and public talks to a broader public during the summer months. These outreach activities were organized in collaboration with the Instituto de Astrofisica de Andalucia (IAA).


The operation of the Plateau de Bure Interferometer in 2010 has been as exciting as in previous years, characterised by outstanding scientific results and a number of major technical achievements.

A first technical breakthrough was achieved in the spring: WideX, a broadband correlator with 3.6 GHz frequency coverage in each polarization, a channel spacing of 2 MHz, and a modular design to support an array extension to 8 antennas, went into operation after several weeks of intensive testing. The new correlator, which is operated in parallel to the narrow-band correlator, is working well since then and shows excellent performance.

The next highlight was reached at the end of the year when Band 4 (275 to 373 GHz) was opened to the astronomical community. The full integration of the ~100 GHz wide band called for a number of system upgrades among which the most sig ni fi-cant were: the installation of the remaining eight Band 4 mixers (two antennas were already equipped in 2009), a complete refurbishment of the local oscillator transport system, a major modifi cation of the system control software and a thorough refitting of the data acquisition software. After months of preparatory work, three weeks during which the array was not available for astronomical observations, and a few days of testing at the beginning of December, the instrument com-missioning team reported the successful measure-ment of interferometric fringes using Band 4. The commissioning was carried out in two phases: after a short technical validation of the instrumental performance over the Christmas period, a series of

science demonstration programs was observed that gave a first glimpse of the exciting new observing possibilities the new band was opening up. First images from the commissioning and science demon stra tion phase revealed the power of the interferometer (see Science Section) and helped to identify areas where work had to be done to improve operational reliability. The performance of the Band 4 system has met our highest expectations. By opening the new band to astronomical research, it has now become possible to observe with a spatial resolution of ~0.2” in the most extended con figuration of the interferometer, and with unprecedented details when observations are made with the instantaneous sensitivity of the broad-band correlator. Regular user-requested Band 4 observa tions have been scheduled and successfully obtained since the beginning of 2011.

While much of the focus at the Plateau de Bure Interferometer has been on Band 4 and the new correlator, the project to develop and implement additional logic to provide full-Stokes polarization imaging capabilities to the system has also been making progress in 2010. A digital switching circuit was implemented that interconnects the polarization IF bandsplitters of different antennas to compute all possible parallel- and crossed-handed correlation products. The project, which is being carried out in collaboration with the Observatoire de Bordeaux, generated a first scientific result, which provided a first proof of concept for a possible implementation of a polarimetric observing mode for users of the Plateau de Bure Interferometer.

oBservations

The interferometer performed according to expectations with almost no downtime due to hardware upgrades. The receivers and the antennas all worked well throughout the year. Observations were done in periods of excellent phase stability and atmospheric transparency at the beginning and at the end of 2010, and faced rather unseasonable conditions in spring. The excellent weather con-

di tions at the end of the year were used for the com missioning and science verification of Band 4. The move to the A configuration was deferred to January 5, 2011, and was so accomplished about two weeks later than in the winter 2009/2010. As in previous years, the scheduling of the A configuration was readjusted shortly after the beginning of the winter scheduling period to optimize the observing of A-rated projects with respect to Sun avoidance limitations and weather constraints. As of February 8, 2011, 41 A-configuration tracks, corresponding to 22 astronomical programs and 6 Band 4 programs, were observed with remarkable sensitivity and successfully completed.

As in previous years, the percentage of telescope contiguous correlation time scheduled for observing programs was on average 50% percent of the total time. Additional 20 percent have to be accounted for receiver tuning, testing equipment, surface adjust-ments and antenna maintenance, and on com plet-ing the commissioning and science verification of WideX, the new LO transport system and band 4; the remaining 30% were lost because of precipitation, wind and inadequate atmospheric phase stability.

The Program Committee met twice during the year, around four weeks after the deadlines for submission of proposals and reviewed 220 applications. The April meeting was seriously disrupted due to travel difficulties resulting from the Icelandic volcano eruption. As a result the Program Committee met for the very first time via telephone conference to Grenoble from their home institutes. More than

170 different projects, including 4 Large Programs and 21 proposals for Director’s Discretionary time, corresponding to 112 different observing programs, were scheduled at the Observatory in 2010. As in previous years, the weight on extragalactic research remains considerable with about twice as many proposals submitted than in the field of young stellar objects. Also, a large amount of observing time was invested in D-configuration between spring and fall in the detection of line-emission (mostly of carbon monoxide) in galaxies at high redshift. The second week in May and October was devoted to coordinated 3mm VLBI continuum observations with several participating radio observatories in Europe and the United States. Annex I details all the proposals to which time was granted in the course of the year, and the great number of papers, that were published in 2010 and are based on data obtained at the interferometer, testifies to the high scientific return of the Plateau de Bure Interferometer.

antenna surface iMproveMents

In the context of the antenna surface refurbishment project (which started in 2007), a special effort was made in the antenna maintenance period to resurface the remaining two antennas and thereby resolve the issues related to panel degradation and antenna efficiency losses. Surface refurbishment work started on antenna 1 in the first June week and was completed on July 3, 2010. On antenna 6, work started around the middle of September and was completed at the end on October 16, 2010. As in previous years, the carbon fibre panels were replaced with new precision-machined aluminium panels (by MECACHROME) using a chessboard like technique to reduce the number of iterations required in the process of achieving highest surface precision. In a subsequent series of holographic surface measurements final surface precisions of 45μm (not weighted by illumination) and 46μm were achieved for antenna 1 and 6, respectively.

As in previous years, the surface quality of all the antennas was verified by means of holographic measurements at the end of the maintenance period. Surface panels were readjusted when deemed necessary.

In connection with the plans to compensate for the central gravity sag of ring 1 panels, a fourth mechanical point was added on antenna 4 to support the center of the panels and the achievable surface quality improvement assessed

Plateau de Bure observing time and atmospheric water vapor statistics over the last ten years. The overall correlation time accounts for 50% of the total time in the year 2010. Band 3 (200 – 274 GHz) and Band 4 (275 – 373 GHz) programs and observations in the most extended (AB) configurations are for the most part carried out in the winter months.


by holographic measurements. The support points were installed during the maintenance period 2009 but the final positional adjustments were only made in early 2010. A semi-quantitative assessment of the panels’ stability, obtained over the last months, suggests that the additional support point is instrumental in ensuring the panels mechanical stability and containing the antenna efficiency losses. Based on this assessment, it is planned to equip the remaining five antennas with a fourth mechanical point in the maintenance period 2011.

Aperture phase patterns of antenna 1 (left) and 6 (right), respectively after the surface refurbishment. A series of holographic surface measurements was needed to readjust the primary surface of the refurbished antennas to a precision of 45μm rms (left) and 46μm rms (right). Contours are given in steps of 100μm.

The strong astigmatism-like deformation detected on antenna 3 in the summer 2009, and repeatedly observed over the winter period 2009/2010, was found to be unrelated to deformations of the secondary mirror. The deformation having disappeared without any apparent reason in the spring 2010, a physical origin for the deformation could neither be identified, nor be demonstrated.

antenna stations

Accurate knowledge of the antenna positions is of paramount importance to adequately compensate for the geometrical delay. In 2009, the inclination angles of the azimuth axis of some of the antennas were found to change significantly over a period of several weeks. Detailed investigations revealed that the changes in the antenna inclination appear to be linked to positional instabilities of the station on which the antennas are clamped, and that these changes occur more often in the spring, when warming conditions bring melting snow and heavy precipitation. To remedy this problem, the antenna inclination is now monitored over time to ensure the best possible relative antenna positions at any time.

antenna sun avoidance

In the context of the antenna primary surface refurbishment plan, Sun illumination measurements were started in 2008 to investigate the possibility of relaxing the initial Sun avoidance constraints (45 deg). The results of these investigations led to the design of a new Sun sensor that will permit observations down to a Sun distance of 25 deg. A first step was made in 2009 with the old sensors by reducing the Sun avoidance circle to 35 deg, and a second was planned for 2010 with the new sensors by reducing it further down to 25 deg. By relaxing the Sun avoidance constraints from 45 deg to 25 deg, the region of the sky inaccessible to observations on any given date will become less than 5%, and will make many more objects of the sky accessible to observations in the extended configurations of the array. Due to the exceptionally heavy schedule of activities at the Observatory during the summer maintenance period 2010, the decision was made to limit the installation of the Sun sensors to only one antenna and to defer the installation of the remaining sensors to the antenna maintenance period 2011.

receiver Band 4 and lo transport systeM

Significant efforts were made in the context of the project to equip the antennas with the Band 4 (275 – 373 GHz) receiving system: 1) the ageing HP synthesizers were replaced each with Rohde & Schwarz frequency generators to meet the tight constraints on phase stability, 2) the Local Oscillator transport system was refurbished to a) accommodate a pair of diplexers (one for each reference) to transport the phasing references (0.5


MHz and 100 MHz) and the generator frequency (1600-2000MHz) over a single coaxial cable, and b) replace the out-dated, mechanically driven LO1 reference signals with YIG voltage controlled oscillators that feature broadband operation (13.2-16.4 GHz) and a much better phase noise performance, 3) the LO1 boxes of Bands 1-3 were modified to match the new reference signals, and the antennas all equipped with band 4 LO1 boxes, 4) the receivers of the remaining 4 antennas were finally fit up with 2SB ALMA-type Band 4 mixers operated SSB.

To manage the structural changes and adapt to the changing system, it was decided to suspend all astronomical activity at the Observatory on August 31, 2010. Operation restarted with 3 antennas (1, 2 and 5) after two weeks of testing and bug fixing, and was resumed entirely with all six elements of the interferometer at the end of the antenna maintenance period (October 17, 2010). The only drawback is the loss of a failing vertical polarization mixer on antenna 1 because of an open-circuit. It is planned to replace the inoperative mixer during the antenna maintenance period 2011.

data arcHive

As in previous years, in a continuing and successful effort with the Centre de Données astronomiques de Strasbourg (CDS), data headers of observations carried out with the Plateau de Bure Interferometer are conjointly archived at the CDS, and are available for viewing via the CDS search tools. In 2010, the archive contained coordinates, on-source integration time, frequencies, observing modes, array configurations, project identification codes, etc. for observations carried out in the period from January 1990 to May 2010. The archive is updated at the CDS every 6 months (May and October) and with a delay of 12 months from the end of a scheduling semester

in which a project is observed in order to keep some pieces of information confidential until that time.

seventH scHool on MilliMeter interferoMetry

The Seventh IRAM Millimeter Interferometry School took place from October 4 to 8, 2010, at the IRAM headquarters in Grenoble. The school focused on both theoretical and observational aspects of millimeter interferometry. In-house and invited experts gave lectures. The program of the school was structured to provide the participants with a broad base knowledge of the Plateau de Bure Interferometer and its future upgrades and a particular accent was given on ALMA. Participants had the opportunity to present posters on their own work and discuss results obtained with the Plateau de Bure Interferometer to share their knowledge and learn from each other’s experience. The school was limited to a total of 63 researchers from Europe and overseas: Germany/ESO (19), France (13), Netherlands (2), Spain (8), USA/Canada (4), Chile (4), United Kingdom (3), Denmark (2), Argentina (1), Finland (1), Italy (2), Bulgaria (1), Ireland (1), Portugal (1) and Switzerland (1). The lectures of the 7th Interferometry School and the proceedings from previous Interferometry Schools are available on the IRAM Web. The school received financial support from the RadioNet (FP7) initiative of the European Commission. The funding was used to pay the meal costs for participants, accommodation and missions for the outside lecturers and accommodation costs for selected participants. No school fees were charged to participants.

Five astronomers were appointed to the group at the end of 2010. The group also received the support of Ivana Stoklasova-Orlitová, a visiting astronomer from Prague on a three months stay.

In 2010 assistance was given to 30 investigators from Europe and overseas visiting IRAM Grenoble for a total of 130 days to reduce data from the Plateau de Bure Interferometer. Advice and support was also provided to a number of experienced astronomers from Bonn, Bordeaux, Cambridge, Garching, Heidelberg and Caltech to reduce and analyze Plateau de Bure Interferometer data remotely from their home institutes. Having suffered from a severe computer network attack early this year, the protection of the IRAM’s computer network was reviewed and it was decided to limit remote access to specific machines for data reduction purposes.

radionet users

Since January 2004, travel funds have been made available to RadioNet eligible astronomers from non IRAM partner countries for expenses incurred during their stay at IRAM for reducing data from the Plateau de Bure Interferometer. These funds which were initially made available by the European Commission in the frame of the FP6 program, are today managed by the FP7 program. For the year 2010, the Program Committee received 27 eligible proposals and recommended 15 proposals for observations with the Plateau de Bure Interferometer. Taking into account proposals accepted in 2008 and 2009 but continued in 2010, time was allocated to 14 eligible proposals corresponding to a total of 266 hours of observing time. Since the beginning of RadioNet, access time was allocated to 78 eligible proposals (12 in 2004, 11 in 2005, 11 in 2006, 13 in 2007, 14 in 2008 and 6 in 2009) for observations with the Plateau de Bure Interferometer, corresponding to a total of ~1900 hours (272 in 2004, 239 in 2005, 272 in 2006, 326 hours in 2007, 334 in 2008 and 140 in 2009) of observing time. User responses to questionnaires of the EU show that IRAM continues

to maintain an excellent reputation concerning the assistance and service given by scientists and support staff to visiting astronomers.

vlBi news

In early 2010, it was necessary to re-test the Plateau de Bure VLBI capabilities: the arrival of WideX had led to numerous hardware and software modifications that could have impacted the VLBI part. Instead of fully disabling WideX in VLBI mode, it was decided to keep it as a parallel backend for pointing, focus and flux estimates. It turned out to be impossible to fully align both WideX polarizations in phase while in VLBI mode: the phase offsets would impact the narrowband correlator during a phasing observation, and lead to a wrong alignment of the individual antenna phases during VLBI. Real-time pointing and focus had therefore to be limited to one WideX polarization only, but even so, the tremendous gain in bandwidth (3.6 GHz compared to the 128 MHz of the narrowband correlator in VLBI mode) provided a significant improvement. For the offline flux calibration, it was possible to calibrate the phases separately and thus use both polarizations.

During the Global Millimeter VLBI Array (GMVA) campaign on May 6-11, both IRAM observatories suffered from difficult weather conditions. Pico Veleta observed 53% of the scheduled scans, and Bure 50%. When not counting the scans impossible for Bure due to the sun avoidance of 35 degrees, the Bure fraction improves to 54%. This relatively small difference shows that the reduction of the sun avoidance circle from 45 to 35 degrees for the winter 2009/2010 season had a positive impact on the rather rigid VLBI observing schedule.

In the October 8-11, 2010 GMVA session, the respective observing fractions of Pico Veleta and Bure were of 33% and 94%. Previous tests in 2010 had shown that both IRAM observatories were capable of doing VLBI at 230 GHz. After the end of the Global campaign, the PI of a pending 230 GHz VLBI project asked explicitly to start the project

RadioNet observing time was allocated to eligible principal investigators from United Kingdom (percentage of total time is 54%), Italy (38%), the Netherlands (4%), Denmark (1%), Hungary (1%), Portugal (1%), Sweden (1%) and Switzerland (<1%) with a slightly unbalanced distribution between PhD students and post-doctoral researchers (31%) and senior scientists (69%).


although the conditions were sub-optimum (the principal source was about to enter a long sun avoidance period). Even so, fringes of high quality were found, which proves that (i) the Bure array phasing works at a sufficient stability and (ii) that the Bure LO chain with its R&S SMA100 B22 frequency synthesizer at the place of the Racal Dana can successfully operate at high frequencies.

In late 2010 it became necessary to refill the hydrogen storage of the Plateau de Bure EFOS-38 maser: the hydrogen storage monitoring showed a telltale non-linear drop that indicated a remaining operation time of a few months. The refill operation was done on the mountain by a T4Science technician. The maser was back into operation after a few hours and is working fine since then.

tHe 22GHZ radioMetric pHase-correction systeM

The 22 GHz radiometer system on the Plateau de Bure antennas underwent several improvements in 2010. In June, the radiometer on antenna 3, which showed a dysfunction in its load arm and an elevation-dependent gain drift, was replaced by the spare. The problems were resolved in the Grenoble frontend laboratory, so that a fully functional spare is again available. New control cards based on the NTP antenna time solved the PPS timing problems that had been noted in particular on Antenna 2. In the real time acquisition, a command was introduced to enable or disable a sliding three-second averaging window on the raw radiometer data. This allows trading time resolution against a better signal-to-noise of the phase correction when the atmosphere is very stable, and was successfully applied from December 2010 on.

Around the time of the installation of the astronomical Band 4 receivers, an occasional interference problem was noticed on the low-frequency channel of the radiometers. Triangulation experiments showed that the source was likely to be inside the receiver cabins, and was traced to a component of the new Band 4 LO boxes that enters the first radiometer band above a certain Band 4 observing frequency. Three simultaneous approaches were put in place to reduce the impact: (i) setting the frequency of the LO box on a safe «parking position» when Band 4 is not used, (ii) developing a passive shielding in the LO box; a first antenna is already equipped and shows that the approach is efficient, and (iii) the development of an offline “dual frequency” radiometer scheme that allows to recover most of the continuum phase correction on contaminated data. Considering that Band 4 observations are typically scheduled when the atmosphere is already close to perfection, the impact of the interference has been very limited.

On the subject of the phase correction tools, substantial progress has been made in the extension of the time range of the phase correction. These tools are so far experimental, but will soon enter the main CLIC distribution.


sis Group

During 2010, the fabrication of the total number of required SIS junctions for the ALMA Band 7 project has been successfully achieved and the focus of the group has shifted to new developments and projects. New designs of junctions for broadband 2SB mixers in the 230 GHz window, as foreseen for NOEMA, were fabricated and work to stabilize the process yield for multi-junction devices continued. In early 2010, the SIS group accepted and commissioned a new deposition system (PLASSYS 500S) that will allow considerable improvement of thin film development by exploring new material and process combinations unavailable so far. The deposition system has been custom designed and enables easy change of sputter targets while combining RF/DC sputtering with a multi crucible Ebeam evaporation station. The machine provides fully programmable automatic process control and was one of IRAM major investments in 2010.

The development of thin films and structures for kinetic inductance detectors (KIDs) has grown into a major activity during 2010. Various designs of lumped element KIDs were produced and different qualities of aluminum film parameters explored. The produced detectors allowed a second run with the NIKA instrument in October 2010 with greatly improved sensitivities at 2mm. Other very promising materials such as NbN and TiN have been explored and essential process steps such as film deposition and etching as well as film characterization utilities has been established. Work on passive millimeter wave structures using silicon technology and surface mounted MEMS technique was pursued. Deposition of Si and SiN membranes and their patterning started with the goal to support advanced millimeter wave-guide coupling structures as designed by the IRAM receiver group. Ongoing work to improve the process for metallic surface mounted variable capacitors addressed the ‘sacrificial layer’ preparation and release process.

frontend Group

The year 2010 was a busy year for the Front End group with maintenance, upgrade, and development activities for both IRAM observatories. Local Oscillators (LO) and cryogenic RF modules for Band 4 were installed on the Plateau de Bure antennas and the LO modules of Bands 1, 2 and 3 were modified to be compatible with the new reference (LO1ref ). A 3 mm HEMT receiver was built and installed on the Pico Veleta telescope and a new mixer for EMIR Band 3 was developed. Construction of a spectrum slicer for a FFT backend has started and good progress was made on the design of the 3 mm band 5x5 multibeam receiver, both for the Pico Veleta telescope.

PLATEAU DE BURE INTERFEROMETER UPGRADE AND MAINTENANCETwo cryogenic cold heads were replaced on antennas 5 and 6 after four years of continuous operation. Following degradation in performance, one of the 22 GHz water vapour radiometers was replaced with a spare unit. A 4-8 GHz cryogenic amplifier was replaced in antenna 1 after installation of the new Band 4 RF module.

The characterization of the Band 4 RF modules (275-373 GHz band) was completed in the lab and receiver noise measurements were performed using one of the new electronically tuned Local Oscillators (see below). The Band 4 RF modules were installed in antennas 1, 2, 3 and 6 (not yet equipped in 2009). The Band 4 RF module of antenna 4 (with a SIS junction in open circuit after a cool down) was replaced with a new one. In antenna 1, one of the two SIS junctions of the 2SB mixer Band 4 module of V polarization is open-circuited.

A new first LO reference signal (13.2-16.4GHz - LO1ref ) for the mm-waves local oscillator modules was developed by the IRAM backend group and all mm-wave LO modules of Bands 1, 2 and 3 were modified to be compatible with the new reference. New harmonic mixers with integrated diplexer were developed and installed inside existing LO modules to replace old units. The modified LO modules (3 Bands x 6 antennas plus spares) were installed on the Plateau de Bure antennas in September 2010.

ELECTRONICALLY TUNED LOCAL OSCILLATORS FOR PLATEAU DE BURE BAND 4A series of eight 283-365GHz electronically tuned Local Oscillators (LO) for Band 4 of the Plateau de Bure interferometer was built and characterized. The design of the Local Oscillator, described in previous annual reports, is based on a commercial 15.7-20.3GHz YIG oscillator cascaded with an active multiplier chain (AMC) and a 3 mm band power amplifier (PA) module built at IRAM. AMC and PA both integrate 94.3-121.6 GHz MMIC amplifiers EBPA107C from NRAO. A commercial frequency tripler, with efficiency of the order of 3%, delivers the final frequency signal. The tripler is cascaded with a cut-off attenuator which reduces the LO noise contribution to a level comparable to that delivered by a Gunn oscillator. The measured output power of the 3 mm band LO module (before tripler) is in the range of 8-50 mW. The output power across 283-365GHz, after a ~4 dB room temperature attenuation, lies between 50 and 270 μW for all eight LO modules of the series; this output power is large enough to pump the Band 4 Sideband Separating SIS heterodyne receivers.

The new Band 4 LO system, compatible with the new 13.2-16.4GHz first LO reference, allows to phase-lock on a time scale of order of few seconds (to be compared with the few minutes required with the mechanically tuned Gunn oscillators).

The new Local Oscillators were successfully installed on the Plateau de Bure interferometer antennas and

Band 1 Local Oscillator module modified with new harmonic mixer (highlighted by red rectangle).

the first astronomical observations were performed across Band 4 in late 2010. The new system opened up the sub-millimeter wave window at Plateau de Bure. This was the first time that a YIG-based Local Oscillator was used at the IRAM observatories.

A 3 MM BAND HEMT RECEIVER PROTOTYPE FOR THE 30-METER TELESCOPEA 3 mm band (84-116 GHz) HEMT receiver prototype, designed and constructed at IRAM, was installed at the 30-meter telescope in August 2010. This receiver allows us to test the 3 mm band cryogenic InP MMIC amplifiers technology and to compare its performance with that delivered by the Sideband Separating SIS mixers (2SB) already available at the site (E0 band of the EMIR receiver).

Inside the telescope cabin, a movable flat mirror switches the telescope beam from the HERA receiver to the 3mm HEMT receiver where it is redirected inside the cryostat and coupled into a single corrugated feedhorn whose output is cascaded with an orthogonal mode transducer from NRAO. Two MMIC HEMT amplifiers from University of Massachusetts, cryogenically cooled to 15K, amplify the 3mm signal in each polarization channel.

At room temperature, the signal is then filtered, down-converted and further amplified to provide a final 8GHz IF bandwidth across 4-12GHz, which is compatible with the currently available IF processor.

The noise temperature (SSB) of the HEMT receiver measured in front of the cryostat window is about 55 K across the whole 84-116 GHz frequency range (see figure). The measured total power stability (Allan deviation) is below 3.10-4 for integration times in the range 1-100 sec, better than the specification of the ALMA receivers.

The receiver was successfully used to perform preliminary astronomical observations.

EMIR BAND 3 MIXER UPGRADEA new sideband-separating (2SB) 200-280 GHz SIS mixer with a 4–12 GHz IF band was developed within the European FP7 RadioNet AMSTAR+ work package. The goal of this work package is the development of receiver pixels and LOs for large focal plane arrays. Therefore, the mixer was designed in a very compact way and the usually adopted superconducting coils for the suppression of the Josephson effect were replaced by permanent magnets. The RF part of the 2SB mixer consists of an RF coupler/mixer block combining all waveguide couplers and the two double sideband SIS mixers in one E-plane splitblock. A 4-12GHz IF hybrid coupler developed by CAY also within AMSTAR+ can be connected directly to the 2SB mixer module.

The mixer has been designed to work for RF frequencies between 200 and 280 GHz and over an IF band of 4–12 GHz. Tests of a prototype have shown that the mixer performs very well (see figures) over the design frequency range and even beyond with a flat response across the IF band. The average image rejection lies around -14 dB. This new mixer will replace the currently installed SSB mixer with 4 GHz IF band of EMIR Band 3, thus quadrupling the instantaneous bandwidth of the receiver.

SPECTRUM SLICER FOR THE 30-METER TELESCOPE FFT BACKENDAn IF processor allowing to interface the IF bands from either the EMIR or the HERA multibeam receivers to a Fast Fourier Transform (FFT) spectrometer from Radiometer Physics GmBH is being developed. Two modes are possible: “wideband mode” (4 GHz bandwidth, 200 KHz resolution), and “high resolution mode” (50 KHz resolution, 1.8 GHz bandwidth). The instrument will be able to process eight inputs simultaneously, i.e. 8 x 4GHz=32GHz maximum in wideband mode.

During 2010, the design of the spectrum slicer was completed and a set (24 plus spares) of locked local oscillators was built and tested; then, the first prototype of a complete subunit was put together.

A total of 24 sub-units are to be built to complete the project.

FOCAL PLANE ARRAY RECEIVER FOR THE 3 MM BAND ON THE 30-METER TELESCOPEA 5x5 multibeam receiver for the 3 mm band is being designed for the 30-meter telescope. The receiver will be based on a modular design with broadband input optics, dual linear polarization ortho-mode transducers and sideband separating (2SB) SIS mixers. The design includes a field derotator, which will allow to track the parallactic angle. The study of the overall cryostat design and receiver implementation into the telescope cabin is in progress, as well as the design of the local oscillator distribution scheme into the RF module. Several optical prototype components were fabricated by the IRAM mechanical workshop (corrugated feed horns and double-face mirrors of individual optics).

ALMA BAND 7 CARTRIDGE PRODUCTIONIRAM is responsible for the production (component fabrication and procurement, assembly and test) of 65+8 spares ALMA Band 7 cartridges covering the RF signal frequency range 275-373 GHz. The dual polarization receivers employ Sideband Separating (2SB) SIS mixers and deliver 4GHz IF band per sideband.

The middle of the cartridge production was reached towards the end of 2010. During 2010, nineteen receivers with state-of-the-art performance were delivered and accepted by the project.

Backend Group

In 2010, the backend group successfully delivered the new correlator (Widex) to the Plateau de Bure interferometer and continued its work to prepare for the next generation of correlator.

WIDEX CORRELATOR DELIVERED ON PLATEAU DE BUREOn February 10 2010, all four quarters of the new correlator WideX were installed on the Plateau de Bure correlator room and successfully connected to the rest of the system. An improvement of the

electrical power distribution was required. Soon after its connection, the new correlator was made available for commissioning and then offered to the community for the observations.

During eleven months of permanent operation, only one minor failure was reported. None of the correlator chips showed any sign of dysfunction. Widex is built to accommodate 8 antennas and is currently operated at 15/28 of its capacity. A complete description of Widex can be found at

http://www. iram.fr/IRAMFR/TA/backend/WideX/index.html

NEW LO TRANSPORT SYSTEMThe phase-stabilized reference frequency for tuning the receivers 1st LO’s was moved from the 2 GHz range to 16 GHz. This new frequency plan allows a fast and easy tuning and, in addition, suppresses some spurious lines that were internally generated. It uses a YIG oscillator that provides a more consistent performance than the previous mechanically tuned DRO’s. All six antennas of the Plateau de Bure interferometer have been equipped with this new LO transport system and the production run has made provision for 6 others.

POLARIMETRYSix PIN transfer switches and their driving circuitry were installed on the Plateau de Bure interferometer. Every second, they allow one to swap the H and V IF’s, according to a Walsh function sequence, so that the source polarization information can be extracted.

DIFER PROJECTTechnology for the next (5th) generation for an IRAM correlator is currently under study. A board has been designed that includes a 5-bit, 8 Gsample/sec ADC and a powerful FPGA. It will be used to acquire expertise on synchronization of multiple, multi gigabit data streams. Concomitantly, a polyphase filterbank was designed and simulated. This polyphase filterbank is able to digitally split a 4 GHz band into 64 frequency windows. These elements are the building blocks for a future correlator, featuring high versatility in trading bandwidth versus resolution, and integrating phased array for wideband VLBI. Further information on this new project can be found at

MecHanical Group

In 2010, the staff of the mechanical group dealt with 148 requests for mechanical components. Many of these requests were handled internally, and only a fraction was subcontracted to outside companies.

WORKSHOPThe workshop produced a large number of microwave components, mixers, couplers, and horns for the new generation receivers of the Plateau de Bure interferometer, AMSTAR couplers, and HEMT components. The workshop carried on with the production of the components in the frame of the ALMA Band 7 construction. Despite the tight schedule, the fabrication of the elements was done on time as foreseen.

The workshop was equipped with a new quality control device that optimises the quality control procedure.

DESIGN OFFICE

New Cad files data organisationThe design office succeeded to install a Product Lifecycle Management process dedicated to the 3D Cad files – Solidworks PDM workgroup. Included with the current CAD software, it will play a key role in managing projects, control design revisions and control data access. This software resulted in improving significantly the quality process.

NOEMA projectProgress was achieved on various mechanical projects to upgrade the Plateau de Bure antennas in view of the NOEMA project. In 2010, the main projects dealt with the following issues:■■ Weight reduction on reflector■■ Production cost reduction■■ Back Up Structure of Subreflector■■ Roller cable

Microwave and antenna studiesIn close collaboration with other groups at the institute, the design office worked on numerous mechanical designs that concerned:

■■ Design of new microwave components for Plateau de Bure and the 30-meter telescope

■■ Design and installation of HEMT receiver■■ Leading the manufacturing of 2 set of panels for 2 new reflectors for the Plateau de Bure antennas

■■ Leading, with the team in Granada (Spain), the refurbishment of 1 Azimuth and 1 Elevation gearboxes at the 30-meter telescope.

Technical support for antennasAs in previous years, the technical group closely collaborated with the technical staff on the Plateau de Bure for all aspects dealing with the antennas.

iraM arc node

.The IRAM astronomy support group is involved in several ALMA-related activities and software developments, which are part of a more general effort to develop a node of the European ALMA Regional Center (ARC).

IRAM is deeply involved in the development of one of the key software for the real-time operations of ALMA, the Telescope Calibration (TelCal) software. This software is performing all real-time calibrations necessary to run the array: antenna pointing, focus, baseline measurements, atmospheric parameters, etc. Two IRAM engineers are working on this development. 2010 was a critical year for TelCal, as the array commissioning made large progresses, implying a continuous and important effort to correct, adapt, and maintain TelCal. New functionalities were also added, as atmospheric calibration using loads at several temperatures. Finally, a stand-alone version of TelCal, interfaced to the CASA off-line package, is also being developed, to allow an off-line reprocessing of the real-time calibration.

During 2010, IRAM was also involved in the development of the Observatory Operations Support (ObOps) package. This is a suite of software tools developed to support the handling of the observing programs, from the Call for Proposals to the project completion, as well as the day-to-day real-time operations.

The institute is also responsible for one work package of the EU-funded “ALMA Enhancement”

program. In that context, a new wide-field imaging technique was developed during the last years to be able to properly process large maps obtained with On-The-Fly interferometry. This technique is being implemented and tested in GILDAS. In 2010, the work for the implementation in the ALMA data reduction software, CASA, was started.

IRAM and ESO agreed on a scheme allowing IRAM astronomers to participate to the ALMA commissioning and science verification phase. Following that agreement, an IRAM astronomer spent three months in Chile in summer 2010. This was a very fruitful experience, and as a consequence, the visit of two other IRAM staff members to the Joint ALMA Observatory in Chile is planned in 2011.

The planning and preparation of the IRAM ARC node has continued. While the European ARC core activities are based at ESO Garching, IRAM is one of the European scientific support nodes. The tasks of an ARC node is mostly to form the users to the millimeter interferometry techniques and to the ALMA instrument, and to provide face-to-face support for the data reduction after the data have been acquired. In that context, IRAM intends to build on the existing in-house expertise on millimeter interferometry techniques and on the experience acquired with the institute participation to the ALMA construction. The face-to-face support service provided to Plateau de Bure interferometer users for more than 15 years will be extended to ALMA.

A major achievement during 2010 was the organization of the “Observing with ALMA: Early Science” workshop, that took place in Grenoble, November 29 to December 1. During three days, many practical aspects of the ALMA instruments were discussed and explained to the participants, as, e.g., the time allocation committee, the pipeline, or the key software astronomers will have to use. More than 180 persons registered to that meeting, a large number that required organizing this event not at IRAM but in a larger, more convenient location in Grenoble.

On the long term, having access to the Plateau de Bure/NOEMA and to the ARC node services should place the IRAM users community in the best possible position to get time on ALMA in an extremely competitive environment.

Participants of the “Observing with ALMA: Early Science” workshop held in Grenoble on November 29 – December 01, 2010.


coMputer Group

In the frame of the installation of the new prototype receiver called HEMT at the 30-meter telescope, the computer group was involved in the support of the control and monitoring software. The main features include two specific graphical interfaces for the laboratory and the observations, an automatic LO tuning, a build-in simulator, an embedded SQL database for configuration storing, a XML RPC server for easy integration with the existing observing software. The package was written in C++/Qt.

At the Plateau de Bure interferometer, the 22GHz water vapor receiver software was modified to rely on the IRAM Network Time Protocol (NTP) timeserver for triggering the integration periods and flagging the measures. The old wired time bus was found unreliable for far distant antenna stations.

The Polar switch module with is software was also installed on the Plateau de Bure interferometer. A GUI and XML/RPC commands let the users and applications select the polarizations connected to the correlator.

The installation of the Band 4 receiver at the Plateau de Bure interferometer with its specific LO, based on a YIG tuned oscillator, required a substantial

upgrade of the receiver software. A new simulator window was included and new control and status commands were added. This installation provided an opportunity to improve the software performance by getting rid of Python and by writing everything in C++/Qt. Still, in order, to standardize our distribution at the 30-meter telescope and the Plateau de Bure interferometer, the same protocols, SQL database and XML/RPC, are in use.

In general, all front-end software was updated in 2010 and improved to comply with this software framework.

In Grenoble, a study showed the difficulty to continue to work with a Fedora distribution for Linux, as the versions were changing too rapidly and the security support was too short. A free distribution, Scientific Linux, was therefore tested. The releases are synchronized with RedHat Entreprise and their lifecycle is up to 10 years. The selected release 5.5 of May 2010 is now the version installed on the new machines and was available on the 15 personal computers that were set up for the interferometry summer school.

A new NAS with a raw volume of 5TBytes was added for the astronomer user space and the projects.


As a consequence more space is available to the technical and administration staff.

Our IT disaster recovery plan has shown the need of backing up most of our NAS data space. While the data from the Plateau de Bure interferometer is well protected with redundant disks and multi servers located at different places, the NAS user data spaces had no backup. Although the NAS is reliable in its concept nothing could be saved on magnetic media. The volume to backup is in the order of 4Tbytes! A solution with RAID 0 servers was set up. They are linked with optic fiber to the NAS and located in the building basement as far as possible from the computer room. The backup performed over the weekend sustains a transfer rate better than 300Gbytes/s.

An effort is still done to distribute automatically Windows applications or patches. In connection with this distribution, the new accounting software release has been worked out to ease its installation.

Finally, in order to unify the authentications and the information needed to the different OS’es and applications, a development was started that is based on LDAP (Lightweight Directory access Protocol) servers with common records among the Windows and Unix implementations. For authentications, a master Kerberos server is the solution that has been retained.

science software activities

The first goal of the science software activities at IRAM is to support the preparation, the acquisition and the reduction of data both at the 30-meter and the Plateau de Bure Interferometer. This includes the delivery of 1) software to the community for proposing and setting-up observations, 2) software to the IRAM staff for use in the online acquisition system and 3) offline software to end users for final reduction of their data. However, the GILDAS suite of software is freely available to and used by other radio telescopes.

At the 30-meter telescope, the main event of 2010 was the introduction of the first two units of a new backend technology called Fourier Transform Spectrometer (FTS). In combination with the EMIR receivers, these units allow the observer to obtain spectra at a spectral resolution of about 200 kHz on a bandwidth of about 4 GHz. This amounts to about 20000 channels per unit. In the next two years, the 30-meter will be equipped with up to 16 such units. This will represent an increase of the data rate by almost one order of magnitude, which implies

important changes in the acquisition and data reduction steps. For instance, MIRA was upgraded to 1) work in 64 bits mode to benefit from modern computer technology and 2) process smaller chunks of data (subscans instead of scans) to obtain a better synchronization between data acquisition and data processing. This latter improvement is useful to check long scans (e.g., pointing, OTF) at intermediate steps. The advent of broadband spectra at high spectral resolution considerably eases multi-line studies. This triggered a series of changes in the data processing and analysis of such spectra in CLASS. For instance, the possibility to select all the spectra of a file whose frequency axis intersects a given frequency range was introduced. Interfacing line databases (JPL, CDMS, ...) to identify the lines and to model their properties converged. It was developed in collaboration with the Observatoire de Grenoble and it was released as a CLASS extension, named WEEDS. The EMIR broadband receivers have a rejection level of only 13dB. In addition, broadband receivers in the sub-millimeter (e.g., some Herschel/HIFI receivers) are double-side band. This implied the resurrection of double-side band possibilities of CLASS. The software package MOPSIC, which is used to 1) monitor the 30-meter telescope behavior and 2) support the bolometer observations, was maintained. Finally, the new generation of 30-meter telescope time/sensitivity estimators introduced last year for EMIR was extended to the HERA and MAMBO cameras.

At the Plateau de Bure interferometer, three main hardware changes happened in 2010. First, the new broadband WIDEX correlator was installed. Second, the 0.8 mm receivers (Band 4) were commissioned. This implied a change of the local oscillator system. As a consequence annoying parasites were suppressed and the phase stability increased. Last, polarimetry measurements were made possible through the installation of a device, which switches the antenna inputs of the correlators. This enables the system to measure the different polarimetry products in a given time sequence. All these hardware changes implied software changes in the setup, acquisition and reduction of the observations. Specifically, ASTRO was upgraded to reflect changes of the frequency plan induced by the change of the local oscillator system. The softwares to pilot the WIDEX correlator, the frequency synthesizer and the polarimetry switch box were finalized. The other online acquisition softwares (in particular OBS, RDI and CLIC) were also adapted. A large effort was needed to upgrade the pipeline, so that it continues to optimally calibrate most of the projects.

Collaboration with the Observatoire de Bordeaux was started to implement inside CLIC the calibration


of interferometric polarimetry. In the area of imaging and deconvolution, IRAM leads the research and development activities around the interferometric On-The-Fly observing mode in the framework of the European FP6 program ‘’ALMA Enhancement’’. In 2010, the first steps of a new algorithm to image interferometric On-The-Fly data were implemented. In parallel, the acquisition of On-The-Fly data at the Plateau de Bure interferometer was improved and new tests were made. Finally, the configurations of the ALMA GILDAS simulator were upgraded to reflect the advancement of the project construction.

All these developments are based on the common GILDAS services, e.g., a set of common low-level libraries, collectively named GILDAS kernel, which takes care of the scripting and plotting capabilities of GILDAS. Although any effort in this area is not necessarily visible for the outside world, it is extremely important for the life of the IRAM data reduction software. In 2010, the large effort to overhaul the graphical possibilities of GILDAS was continued so that it could be released in 2011. This is a step required to cope with the large increase of data size, which will result from both the improved imaging capabilities of the IRAM instruments and the increase in the number of channels of the upcoming generation of spectrometers. Finally, the support of the more and more popular GFORTRAN compilers and Mac/OSX system was improved.

This impressive number of concomitant software developments is a testimony to the vitality of the team of software developers, which was largely renewed during the last 5 years.

puBlic relations

The year 2010 began with two very spectacular press releases, which both triggered a major echo in the international press. For the first time, it had been possible to pinpoint the location of water in a very young proto-planetary system, analogue to our Sun – thanks to the IRAM Plateau de Bure Interferometer. In addition to this result, another paper was published in Nature reporting the detection and imaging of cold molecular gas in star forming galaxies representative of galaxy populations shortly after the Big Bang. International media picked up both results and IRAM had several articles in international newspapers like the German FAZ, the FOKUS and Scientific American.

In order to continue public outreach work on a regional level, IRAM astronomers continued during all winter season their well-attended series of public

conferences at St. Etienne-en-Dévoluy (in the Hautes-Alpes near the Plateau de Bure).

After the brochure and the web page, the IRAM Newsletter got an overall “re-looking”. It is published twice a year (in February and July). The new edition, called “IRAMInfo”, has a completely new layout and is only available electronically. Special emphasis is given to scientific results, technical developments and reports on the large observing programs.

At the end of spring, preparations for the 7th IRAM Interferometry Summer School started. The school took place on October 2010 with more than 70 participants and lecturers working together during open sessions and tutorials.

Right after the Summer School, the IRAM ARC Node organized a workshop about Early Science with ALMA. During three days, more than 140 participants and lecturers exchanged information and latest news about ALMA, the first call for proposals and early observations.

At the end of the year, IRAM took part, for the second time, in the French national science festival Fête de la Science. With an interactive and movable model of the Plateau de Bure Interferometer, a 3-D film, live observations with a telescope in Sweden (thanks to the Hands-On-Association) and presentations about our Solar System, the institute’s exhibition stand attracted a lot of visitors. About five school classes per day and more than 11000 people in total visited the IRAM stand.


Personnel and finances

The IRAM administration comprises 3 groups in charge of the areas as of human resources, finances and general services.

HuMan resources

In 2010, 105.5 positions were foreseen in the personnel plan authorised by the IRAM Executive Council, i.e. 77.7 for France and 27.8 for Spain. 11 additional positions are authorised for Post-docs and thesis students.

In addition to these authorised positions, IRAM also has a number of staff recruited for specific activities such as ALMA contracts and European contracts.

In total, IRAM employed a total of 146 persons (132 FTE) in 2010.

finances

The activity of the IRAM administration in the area of finances covers the budget preparation and management, the annual accounts and the liaison with the auditors and the audit commission. The overall is reported on a yearly basis to the Executive Council.

IRAM’s financial situation in 2010, as well as budget provisions for 2011, are summarised in the following tables.

The associates approved a 2% increase in their base contribution to the operational budget of 2010. They also agreed upon a further increase by 2% for 2011. The contributions to the investment budget were maintained at their previous level for 2010 and 2011. In addition, the associates finance the reconstruction of the cable car to access the plateau de Bure observatory.

The IRAM administration completed a global review of the IRAM insurance package that was started in 2009. The revision is now finished and a new company has been hired to deal with IRAM insurance.

Front Cover

View of the Orion nebula, the closest region of massive star forming region, in the 12CO(2-1) emission, that traces the distribution of the cold (10-100 K) molecular gas. The map was obtained using HERA at the 30-meter telescope and has spatial resolution of 12” (or 0.025 pc). The dynamics of the molecular gas are shown in blue (for the emission with velocities between –5 and 8 km/s) and in red (for velocities between 12 and 25 km/s). The map in green shows the emission from warm (100 to 1000 K) dust and gas at the surface of the clouds, traced at 8 microns by the Midcourse Space Experiment satellite.

The Institut de Radioastronomie Millimétrique (IRAM) is a multi-national scientific institute covering all aspects of radio astronomy at millimeter wavelengths: the operation of two high-altitude observatories – a 30-meter diameter telescope on Pico Veleta in the Sierra Nevada (southern Spain), and an interferometer of six 15 meter diameter telescopes on the Plateau de Bure in the French Alps – the development of telescopes and instrumentation, radio astronomical observations and their interpretation.

IRAM was founded in 1979 by two national research organizations: the CNRS and the Max-Planck-Gesellschaft – the Spanish Instituto Geográfico Nacional, initially an associate member, became a full member in 1990.

The technical and scientific staff of IRAM develops instrumentation and software for the specific needs of millimeter radioastronomy and for the benefit of the astronomical community. IRAM’s laboratories also supply devices to several European partners, including for the ALMA project.

IRAM’s scientists conduct forefront research in several domains of astrophysics, from nearby star-forming regions to objects at cosmological distances.
