The orbital velocity anisotropy of cluster galaxies: evolution
Context. In nearby clusters early-type galaxies follow isotropic orbits. The orbits of late-type galaxies are instead characterized by slightly radial anisotropy. Little is known about the orbits of the different populations of cluster galaxies at redshift z > 0.3. Aims. We investigate the redshift evolution of the orbits of cluster galaxies. Methods. We use two samples of galaxy clusters spann...
متن کاملCluster Selection and the Evolution of Brightest Cluster Galaxies.
The K-band Hubble diagram of brightest cluster galaxies (BCGs) is presented for a large, X-ray-selected cluster sample extending out to z=0.8. The controversy over the degree of BCG evolution is shown to be due to sample selection since the BCG luminosity depends on the cluster environment. Selecting only the most X-ray luminous clusters produces a BCG sample that shows, under the assumption of...

15 صفحه اولSurface-brightness Evolution of Cluster Galaxies
Surface brightness evolution has been detected in elliptical galaxies (consistent with passive evolution models of old stellar populations) and in disk galaxies (presumably due to enhanced star-formation rates). The rates of evolution in clusters and the field are not measurably different. In addition to this similarity, the high-redshift populations in both environments exhibit a “blue-excess”...
متن کاملEnvironmentally-driven Evolution of Simulated Cluster Galaxies
Galaxies in clusters are gas-deficient and a number of possible explanations for this observation have been advanced, including galaxy-cluster tidal interactions, galaxy harassment, and ISM-ICM gas stripping. In this paper, we use a cosmological simulation of cluster formation and evolution in order to examine this issue from a theoretical standpoint. We follow a large number of galaxies over t...
