Observing the build – up of the colour - magnitude relation at redshift ∼ 0 . 8 †
We analyse the rest–frame (U−V) colour–magnitude relation for 2 clusters at redshift 0.7 and 0.8, drawn from the ESO Distant Cluster Survey. By comparing with the population of red galaxies in the Coma cluster, we show that the high redshift clusters exhibit a deficit of passive faint red galaxies. Our results show that the red–sequence population cannot be explained in terms of a monolithic an...

متن کاملThe VIMOS VLT Deep Survey ⋆ : The build - up of the colour - density relation
We investigate the redshift and luminosity evolution of the galaxy colour-density relation using the data from the First Epoch VIMOS-VLT Deep Survey (VVDS). The size (6582 galaxies with good quality redshifts), depth (IAB ≤ 24) and redshift sampling rate (20% on the mean) of the survey enable us to reconstruct the 3D galaxy environment on relatively local scales (R = 5hMpc ) up to redshift z ∼ ...

Origin of the colour-magnitude relation of elliptical galaxies
Evolutionary models of elliptical galaxies are constructed by using a new population synthesis code. Model parameters are calibrated to reproduce the observed colour-magnitude (CM) relation of Coma ellipticals in V −K vs. MV diagram. The SEDs are degenerated in stellar age and metallicity. An attempt is performed to break this degeneracy, by simulating evolution of the CM relation of elliptical...
