On the formation of massive galaxies: A simultaneous study of number density, size and intrinsic colour evolution in GOODS
Ignacio Ferreras, Thorsten Lisker, Anna Pasquali, Sadegh Khochfar, Sugata Kaviraj
The evolution of number density, size and intrinsic colour is determined for a volume-limited sample of visually classified early-type galaxies selected from the HST/ACS images of the GOODS North and South fields (version 2). The sample comprises 457 galaxies over 320 arcmin2 with stellar masses above 3E10 Msun in the redshift range 0.4<1.2.
