Resumen:
We investigate the origin of the color-magnitude relation(CMR) observed in cluster galaxies by using a combination of cosmo-logical N-body/SPH simulations of galaxy clusters, and a semi-analayticmodel of galaxy formation (Lagos, Cora & Padilla 2008). Simulated re-sults are compared with the photometric properties of early-type galaxiesin the Antlia cluster (Smith Castelli et al. 2008). The good agreementobtained between observations and simulations allows us to use the infor-mation provided by the model for unveiling the physical processes thatyield the tigh observed CMR.
