Modeling the Color Magnitude Relation for Galaxy Clusters

Cosmology and Nongalactic Astrophysics 2011-06-20 v1

Abstract

We investigate the origin of the colour-magnitude relation (CMR) observed in cluster galaxies by using a combination of a cosmological N-body simulation of a cluster of galaxies and a semi-analytic model of galaxy formation. The departure of galaxies in the bright end of the CMR with respect to the trend denoted by less luminous galaxies could be explained by the influence of minor mergers
