The evolution of active galaxies in clusters

Research output: Contribution to journalArticlepeer-review

Abstract

The results of deep radio, sub-mm and X-ray observations of samples of high redshift (zsimilar to1) clusters are presented. These reveal significant excesses of active galaxies associated with the clusters at all three wavelengths. The cluster radio source population shows evolution consistent with the (1+z)(3) evolution typical of many AGN classes. A large fraction of the AGN are hosted by apparently passive early-type galaxies, often with a close companion. These results essentially constitute the detection of a counterpart of the Butcher-Oemler effect for both strongly starbursting galaxies and AGN.
