(host: Shardha Jogee) "The XMM Cluster Survey (XCS): Results from the First Data Release"

Clusters of galaxies provide an opportunity to explore the underlying cosmological model and the processes governing structure formation and so several large-area surveys for clusters are currently underway. In this talk I will present the XMM Cluster Survey, a search for serendipitous galaxy clusters in archival XMM-Newton data, using the signature of X-ray extent. The main goals of the survey are to measure cosmological parameters, trace the evolution of X-ray scaling relations, and investigate galaxy evolution in the densest environments. I will present the X-ray and optical methodology used to construct the XCS first data release (XCS-DR1); a catalog of 503 galaxy clusters of which 401 have measured X-ray temperatures. I will then feature some results derived from this catalog; highlighting investigations into the evolution of the X-ray luminosity--X-ray temperature scaling relation, the impact of AGN feedback on the intracluster gas, and the halo occupation of BOSS galaxies within XCS clusters.
