Scientific paper

Poor clusters may be the best laboratories for studying the effects of environment on galaxy evolution. Some poor clusters are claimed to have cooling flows; however, with current satellites, it is impossible to determine if the central X-ray excess is due to a cooling flow, an AGN, an X-ray luminous galaxy, or all three. We propose to use the high spectral and spatial resolution of AXAF to measure temperature and abundance gradients in poor clusters. We will determine the relative contributions to the central X-ray emission from all three sources listed above. These observations will also allow us to constrain the amount of mixing between the central galaxy and the intracluster medium, and the Lx-Lopt relation for 20-30 idividual galaxies expected to be detected in 3 poor clusters.
