Radio-Active CoWS: Probing the Role of Environment on Radio-AGN at z~1 with MaDCoWS

Emily Moravec

AGN properties and dense environments are connected in a myriad of ways. For galaxies, the hot gas found in dense environments can impact AGN fueling and confine AGN outflows. Meanwhile, feedback from AGN jets can have a significant mechanical and thermal impact upon the surrounding gas. To better understand the interplay between AGN and the hot intracluster medium in galaxy clusters, we have been investigating the distribution of AGN and properties of the AGN population associated with z~1 galaxy clusters from the Massive and Distant Clusters of WISE Survey (MaDCoWS). I will first give an overview of MaDCoWS, which is the first cluster survey capable of discovering massive clusters at these redshifts over the full extragalactic sky, and will discuss key results from this program. I will then focus upon our studies of the AGN population. I will first discuss the distribution of AGN relative to the clusters. Then, I will present the results from a study with the JVLA to determine the radio morphologies of extended radio sources and the properties of their host-galaxies in a sub-sample of ~50 MaDCoWS clusters. Using optical, infrared, and radio data, we investigate correlations between the size and luminosity of the radio-AGN with stellar mass, cluster-centric radius, and cluster richness. We find a remarkable diversity of radio galaxy and host galaxy properties across a range of cluster properties.
