plus 5 post-doctoral research fellows
Sebastien Foucaud, Meghan Gray, Mustapha Mouhcine, Osamu Nakamura & Jun Pan
plus 15 postgraduate students.
Associated member: Reynier Peletier (Groningen)

MEGHAN GRAY (+COMBO-17)
Environment and galaxy evolution mass weak lensing gas: X-rays galaxies: SEDs from COMBO-17, dynamics from 2dF,
obscured SF from Spitzer, morphologies from HST/ACS
17-band imaging + lensing mass map: see clear spatial segregation of bimodal galaxy population
lensing reveals surface mass threshold for truncation of star-
formation

ALFONSO ARAGON-SALAMANCA
Galaxy formation and evolution in different environments

The links between morphology, stellar populations and environment
The evolution of star formation in the universe
CL1354.1-1231
z=0.76
Galaxy formation and evolution in different environments:
The ESO Distant Cluster Survey
CL1232.3-1250z=0.54
Obtain a uniform imaging and spectroscopic database for a large and representative sample of galaxy clusters covering at least half of the Hubble time
Characterise the sizes, luminosities, morphologies, internal kinematics, star formation and stellar populations of cluster galaxies.
Compare cluster samples at z=0.8, 0.5 and 0.1 (SDSS) to establish trends as a function of redshift exploring a large cluster mass range
Compare with high-resolution simulations of galaxy and galaxy cluster formation to determine the role of the relevant physical processes
The origin of galaxy morphology:
The formation of S0 galaxies
Tully-Fisher relation of high-z spirals (with Osamu Nakamura, Bo Milvang-Jensen & Steven Bamford)
Tully-Fisher relation of low-z S0s (with Alejandro Garcia-Bedregal and Mike Merrifield)
Globular Clusters in S0s (with Osamu Nakamura and Alejandro Garcia-Bedregal)
IFU studies of the dynamics and stellar populations of cluster E+A S0s at intermediate redshifts (with Steven Bamford)
The evolution of Star Formation:
H surveys at different redshifts
