Evidence of a link between the evolution of clusters and their AGN fraction

Abstract:

We discuss the optical properties, X-ray detections, and Active Galactic Nucleus (AGN) populations of four clusters at z ~ 1 in the Subaru-XMM Deep Field (SXDF). The velocity distribution and plausible extended X-ray detections are examined, as well as the number of X-ray point sources and radio sources associated with the clusters. We find that the two clusters that appear virialised and have an extended X-ray detection contain few, if any, AGN, whereas the two pre-virialised clusters have a...
