Title: | Ensemble properties of cluster galaxies and their redshift evolution |
Abstract: |
Galaxy clusters represent an excellent laboratory for understanding
various processes involving the galaxies, the dark matter potential,
and the hot intracluster medium. Furthermore, in light of the on-
going large scale cluster surveys (e.g., ACT, SPT, AMiBA), it is of
critical importance that we understand the evolution of clusters
towards z~1.
I will present a detailed analysis of several fundamental properties (spatial distribution, luminosity function, mass-observable scaling relations) for cluster galaxies, trying to answer the following questions: (1) How are cluster galaxies assembled in the context of hierarchical structure formation? (2) What is the redshift evolution of the cluster galaxy population? (3) How is the radio-loud AGN phenomenon related to cluster galaxies, and what might be the origin of the radio activity? |
