SUMMARY:The Evolution of AGN in Clusters of Galaxies\, Astronomy Collo
 quium\, Paul Martini\, Ohio State
DESCRIPTION:Galaxies in clusters have undergone profoundly different e
 volution relative to their counterparts in the field. I will present n
 ew results that show the same holds true for the supermassive black ho
 les at the centers of cluster galaxies. While luminous AGN are nearly 
 nonexistent in local clusters\, they are comparatively common in clust
 ers about z=0.5.<br><br>
\nFurthermore\, the rate at which cluster AGN
  have shut off from high redshift to the present day is substantially 
 faster than the decline in the space density of field AGN. The evoluti
 on of the cluster AGN population therefore appears to mirror the evolu
 tion of cluster star-forming galaxies\, as well as suggest that AGN do
 wnsizing has an<br><br>
\nenvironmental dependence.<br><br>
