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 origin of galaxy morphology

The links between morphology, stellar populations and environment

The evolution of star formation in the universe

CL1354.1-1231

z=0.76

Page 12: Astronomy, Astrophysics & Cosmology at the University of Nottingham

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
