Scientific paper

We have undertaken an archival Chandra study to investigate the AGN content of groups of galaxies. Our sample consists of 23 nearby groups with relatively long Chandra observations. Detected X-ray sources are matched to galaxies with known redshifts in NED to confirm group membership. While we generally find a couple of matches per group, we do not find a population of luminous AGN (>1041 ergs s-1) outside of the group center. However, we do detect central X-ray point sources in most of the groups, and in several cases we detect diffuse emission from group galaxies.
