1 Unresolved X-Ray Sources in Intermediate Redshift Cluster Fields Unresolved X-Ray Sources in Intermediate Redshift Cluster Fields S. Fawcett, A. Hicks, and E. Ellingson (University of Colorado) Introduction Martini et al. (2002, APJL,576,L109), have found an unexpectedly high rate of X-ray point sources in the outskirts of low-redshift clusters, using high spatial resolution Chandra images. Surprisingly, many of these point sources appear to be from AGN embedded in otherwise quiescent, red cluster galaxies. Even more recently, Johnson et al. (2003, MNRAS, 343, 924) have found evidence suggesting that an excess of X-ray detected AGN at high redshift seem to be associated with infalling galaxies. In order to confirm this result for other clusters, we have searched for unresolved X-ray sources around 12 intermediate (0.2
