2003 ANNUAL REPORT1 TO ANU COUNCIL
Penny D. Sackett, Director
1 Overview
Most of the activities of the Research School of Astronomy and
Astrophysics (RSAA) in 2003 were affected in one way or another by
a horrific event that began the year: the devastating Canberra bush
fires of 18 January. The firestorm destroyed or damaged beyond
repair all observing facilities on the mountain, the technical and
workshop building, the heritage Administration Building, and
several homes on Mount Stromlo. As will be evidenced in this
report, however, the achievements of the RSAA were maintained at a
very high standard despite this major setback.
Returning to Mt Stromlo only three weeks after the fire swept over
the mountain was a highlight for all staff. Most could return on 11
February 2003, although some technical staff worked off-site on the
Acton Campus or at ADFA until temporary work accommodation could be
completed later in the year. The RSAA staff is grateful to their
colleagues throughout the ANU who worked to enable a swift and
successful return.
Unfortunately, the physical state of Mt Stromlo has changed very
little since the addition of temporary facilities. The slowness of
the physical recovery and the extraordinarily large fire-related
workload placed on RSAA staff work against the School performing at
its full potential, and require immediate remedy.
A long-awaited highpoint was the launch of the official history of
Mount Stromlo Observatory: Stromlo: An Australian Observatory by
Tom Frame & Don Faulkner (Allen & Unwin, 2003, pp. xix +
364). Both Drs. Frame and Faulkner are Visiting Fellows; Don
Faulkner retired from RSAA after years of service to his discipline
and the Observatory.
S t r o m l o details 80 years of history, from the Observatory’s
beginnings as the Commonwealth Solar Observatory, through its
joining with the ANU and producing the ANU’s first PhD graduate, to
an epilogue describing the catastrophic fires. The Deputy Prime
Minister, the Hon. John Anderson, officially launched the book at
Stromlo in October 2003. A second printing is already
planned.
The medium-term (2003-2007) goals of the RSAA have been codified in
a Strategic Plan1 that was finalized in November, and subsequently
endorsed by the School’s international Advisory Board.
1 RSAA Annual Reports and its Strategic Plan can be found at
http://www.mso.anu.edu.au
The plan begins with the mission statement to:
- Advance the observational & theoretical frontiers of
astronomy and its enabling technologies - Provide national and
international leadership - Train outstanding scientists
and provides guiding principles, objectives, actions and success
indicators to drive a cycle of continual improvement. Developed
with input from all RSAA staff, the plan will serve as a reference
document for charting a path in the next five years that will take
RSAA to an even brighter future while progressing ANU to 2005
goals. Achievements against goals in the RSAA Strategic Plan are
presented next.

3 Summary Reports
3.1.1 Red Giant Stars: Football-shaped
In its old age, a star like the Sun will swell up to become a red
giant of enormous size: the surface of the star reaches out to a
distance comparable to the orbit of Earth. At this time, a typical
red giant will pulsate in and out with a period of about 80 days.
About one quarter of such red giants also show light and
line-of-sight velocity variations with long periods of about 800
days. Associated with these long-period variations is some sort of
surface activity, which is probably due to magnetic star spots
causing a warm chromosphere to come and go.
RSAA researchers Dr Peter Wood and Mr Enrico Olivier, together with
Dr Steve Kawaler of Iowa State University, have tried to understand
these long period variations, and have arrived at an explanation.
The likely cause, they conclude, is that the red giants undergo
large amplitude g (gravity) mode oscillations, essentially
consisting of large bulges that travel around the equator of the
star in about 800 days. According to Wood and collaborators, this
would distort the shape of the star; so that many red giants should
look football shaped when viewed such that the g mode bulges are
perpendicular to the line of sight. The work has been accepted for
publication in the Astrophysical Journal.

by the SOHO
spacecraft)
3.1.2 Nearly a Quarter Million Galaxies: Final public release of
the 2dF Galaxy Redshift Survey
The Two Degree Field Galaxy Redshift Survey (2dFGRS) achieved its
final milestone in July 2003, with the public release of the survey
database at the International Astronomical Union‘s General Assembly
in Sydney. The 2dFGRS team, led by Drs Matthew Colless of RSAA and
John Peacock of Royal Observatory Edinburgh, included Drs Bruce
Peterson, Carole Jackson, Simon Driver and Roberto De Propris of
RSAA, and measured the positions and redshifts for 221,000 galaxies
over five years of observations with the Anglo-Australian Telescope
at Siding Spring. The survey has been an outstanding success, with
major impact on cosmology, large-scale structure studies and
understanding of low-redshift galaxy populations. (Image courtesy

The final database is available to astronomers worldwide on compact
discs. For more information, see
http://www.mso.anu.edu.au/2dFGRS/.
3.1.3 Gamma Ray Bursts: Fast and Steady wins this Race
PhD student Paul Price and Dr Peterson and Prof Schmidt contributed
to a major breakthrough in the understanding of gamma-ray bursts
(GRBs) this year. Using telescopes at Siding Spring Observatory,
they immediately identified the optical light associated with what
is by far the closest (and normal) gamma ray burst yet detected.
Their prompt discovery allowed unprecedented scrutiny of this
object with other telescopes around the world, which showed, among
other things, that this explosion was caused by a supernova, not
dissimilar to a certain class of objects seen in the nearby
Universe known as Type Ic hypernovae. The work was published in a
March 2003 issue of Nature.
3.1.4 Huge String of Galaxies Discovered in the Early
Universe
Dr Paul Francis of RSAA led an international team that mapped an
enormous volume of the early Universe, capturing information about
the Universe when it was only one-fifth the current age.
The RSAA-led team discovered a string of galaxies over 300 million
light years in length. Since the observations revealed only the
brightest few galaxies, what they revealed is probably far less
than 1% of the total mass content in the string, most of which is
invisible dark matter. This is the first time astronomers have been
able to map an area in the early Universe big enough to reveal such
a galaxy structure. (Figure copyright Paul Francis and NASA)
According to current theories, strings of galaxies this large
should not have been able to form so early after the Big Bang. One
explanation may be that the dark matter is not arranged in the same
way as the galaxies we are seeing in the observations.
3.1.5 Close Encounter Garners Public Interest
On 27th August 2003, Mars passed closer to the Earth than at any
point in the last 67,000 years. Public events were organised both
on the ANU campus and in Coonabarabran under the auspices of RSAA,
the ANU’s Planetary Science Institute, the Canberra Astronomical
Society, and the National Institute of Physical Sciences. Both
events were very well attended: over 4000 people in Canberra and
around 500 in Coonabarabran showed up to hear evening talks and
look through telescopes. The event generated extensive media
coverage, with live broadcasts from Coonabarabran on four TV
channels.
3.1.6 Undergraduate Research at RSAA, Including Astronomical
Instrument Design
Sixteen undergraduate students from the ANU’s Faculty of Science,
most of whom were first year students, including several PhB
students, carried out research projects supervised by RSAA staff.
Often their work included first-hand observations using ANU
telescopes at Siding Spring. The projects included building a radio
telescope receiver, searching for the origin of a supernova, taking
data to help design the public outreach camera for a possible
Phoenix telescope to be placed on Mt Stromlo, and pan-spectral
mapping of Mars during its recent close approach.
3.2 Student Statistics and Activities
At the end of 2003, the Graduate Program in Astronomy &
Astrophysics comprised 20 on-course students, four more students
who are completing their thesis with an extension of time to
submit, and one other who was on suspension for medical reasons. Of
this 25 total, 12 are male and 13 female. Nine of the students are
international (Brazil, South Africa, Italy, United Kingdom, Germany
(2), Canada, the Netherlands and New Zealand). In 2003, seven
students entered the program and three students completed their PhD
degrees at RSAA.
Although no PhD projects were severely disrupted by the fires in
January, the resulting aftermath, including the total loss of
possessions by several students, has caused delays in some cases.
One PhD student, Gayandhi de Silva, had planned to make extensive
use of the 74inch telescope on Mt Stromlo. Through the generosity
of Apache Point Observatory in New Mexico, Ms. de Silva was able to
carry out her observations on their 3.5m telescope, which she
operated remotely from Mt Stromlo.
Using a modest sum supplied by the School to PhD students for their
professional development, RSAA students organized an astronomy
conference on Mt Stromlo dedicated to student projects. Students
submitted abstracts, prepared the program, acted as session chairs,
gave talks according to strict guidelines, prepared a conference
summary, and issued a conference program. The result was a roaring
success for graduate students, honours students and academic staff
alike.
A total of seven students from the ANU Faculty of Science did
honours projects with a supervisor from RSAA in 2003. We are
pleased to note that six of these decided to begin a PhD program at
RSAA in 2004. Indeed, with these students and four others, two from
other Australian institutions and two from overseas (Mexico,
Denmark), RSAA will see its largest intake of PhD students in over
a decade.
The School runs a yearly Summer Research Scholar Program. During
the summer of 2002-03 the program was convened by Dr Simon Driver
with eight scholars taking part; two from Griffith University and
one each from Otago (NZ), the University of Tasmania, ANU, Sydney
and Melbourne Universities, and the University of Queensland. The
Stromlo Summer Program provides a regular source of incoming
graduate students to the School.

3.3 New Grants Awarded in 2003
The success rate of RSAA applications to ARC was not as high in
2003 as in the previous two years. To what extent this can be
attributed to the effects of the January bushfires, which preceded
the (extended) ARC deadline by a couple of months, is difficult to
determine, but it surely played a role. Nevertheless, two large
awards were won by RSAA staff in 2003:
(*) USyd administers with participants ANU, CSIRO, Monash,
Swinburne, UMelb, UNSW, USQ.
3.4 Major Prizes, Honours and Awards
RSAA staff and students continued to excel as evidenced by the
honours bestowed upon them in 2003. Perhaps of greatest note is the
recognition from several quarters given to the RSAA team
responsible for the design and construction of the Near-infrared
Integral Field Spectrograph destined for the giant Gemini telescope
in Hawaii before its destruction in the bushfires, and the
remarkable achievement of RSAA as one of the best organizations in
all Australia for producing well-cited scientists. Shown at right
is the NIFS team.

3.5 Budget Performance
In 2003, the School received a block ANU grant of $5,736K, external
revenue of $6,616K, and income from commercial activities of $595K.
The breakdown of the external revenue is provided in the table
below.
RSAA External Income in 2003 Siding Spring Observatory Site
Recoveries $ 365 K Trans-Neptunian Object Project 16 K Univ of
Arizona Near Earth Object Project 192 K Gemini South Adaptive
Optics Imager (GSAOI) Contract 2,759 K Near-infrared Integral Field
Spectrograph Contract (NIFS) 6 K DEST Systemic Infrastructure
Initiative for Siding Spring Observatory 1,854 K ARC awards 1,420 K
ANSTO 4 K Total External Income $ 6,616 K
The two RSAA commercial activities in 2003 were the Siding Spring
Observatory Lodge and Visitors' Centre, and Mount Stromlo and
Siding Spring Observatory (MSSS0) Housing. The Stromlo and SSO
Visitors' Centres were visited by approximately 1,000 and 10,000
people, respectively, in 2003. The dramatic drop in the Stromlo
numbers was due to the fires which closed the site on 18 January
2003. The Siding Spring visitor numbers indicate a disappointing
decrease of 50% compared to the previous year. This decrease is now
being investigated. SSO commercial activities ended the year with
an operating deficit of $7,000, which was offset by accumulated
funds. The MSSSO Housing activity sustained an operating deficit of
$3,435. It should be noted, however, that $53,000 of rental income
for the six Stromlo houses destroyed in the bushfires did not
eventuate in 2003; a claim has been submitted to the ANU's insurers
to recover the lost income.
3.6 Gender Equity Performance
At the end of the calendar year 2003, 13 of the School's 25
postgraduate students were female, compared to 9 of 21 total in
2002. Women represent 16% of RSAA general staff (excluding
casuals). Of RSAA's 26.5 academic staff, three are female, namely
its Director and two researchers on fixed- term post-doctoral
appointments. Despite a policy implemented last year of advertising
more widely and for longer periods of time, the number of female
applicants to academic posts in RSAA is very small: 0 – 10%, and
importantly, smaller than the female ratio of putative applicants
worldwide. The School is beginning to examine why this might be the
case, and to take steps to address this apparent anomaly.
3.7 Future Directions
In the next four years, the directions of the School will be guided
by the RSAA Strategic Plan. One new area of emphasis, planetary
science, is being developed together with the Research School of
Earth Sciences to combine strengths in an emerging
cross-disciplinary field. One appointment has
been made to the joint Planetary Sciences Institute, and three more
positions will be filled in 2004. A joint seminar and dinner series
is enjoying increasing success, with ~80 attendees at the last
event.
The new Advanced Instrumentation and Technology Centre expected to
be a focus of the New Stromlo is being specifically designed with
the future in mind, emphasizing strategic areas of growth for RSAA
astro-engineering in the next two decades: design, high-precision
and adaptive optics, technical study and training, and integrated
systems. The School is beginning to forge links with the best teams
worldwide investigating the science and technology of the Next
Generation Telescopes, including optical-infrared telescopes with
diameters of 20-100m. These linkages promise exposure to worldwide
expertise and an opportunity to contribute in unique ways to
international science to the benefit of ANU and the nation.
