17 Dec 2002 | Subject: | astro-ph | Affiliation: | INAF/Trieste, Leiden Sterrewacht, LAM Marseille | Abstract: | We study the evolution of galaxies in clusters by the analysis of a sample of about 3000 galaxies, members of 59 clusters from the ESO Nearby Abell Cluster Survey (ENACS). We distinguish four cluster galaxy populations, based on their radial and velocity distributions within the clusters. Using the class of ellipticals and S0’s (excluding the very bright ellipticals), we determine the average cluster mass profile, that we compare with mass models available from numerical simulations. We then use this cluster mass profile to solve for the anisotropy profiles of the three other cluster galaxy populations, viz. the very bright ellipticals, the early spirals, and the late spirals with the emission-line galaxies. We discuss the implications of our findings for the evolution of cluster galaxies. | Source: | arXiv, astro-ph/0301343 | Services: | Forum | Review | PDF | Favorites |
