A better understanding of AGN in cluster environments may provide clues to the reasons for their ignition and the subsidence throughout cosmic evolution. Furthermore, if this activity is related to the hierarchical growth of structure, as has been suggested, study of the distribution and nature of cluster AGN will allow us to test structure formation models.
The Deep Lens Survey (DLS) team has identified a unique sample of galaxy clusters through weak gravitational lensing shear mapping (Wittman et al. 2006). Chandra X-ray confirmation of several of these clusters has serendipitously uncovered large numbers of X-ray point sources, presumably AGN, in the fields of these clusters. We report here on our survey to characterize these AGN; determine their redshifts, optical and X-ray luminosities, and distribution relative to the hot gas, galaxies and dark matter mass of their cluster environment.
