Photometric Properties of Low Redshift Galaxy Clusters
Abstract
We have recently completed a comprehensive photometric survey of 27 Abell clusters with the 8k mosaic camera on the KPNO 0.9m telescope. Preliminary luminosity functions and dwarf-to-giant galaxy ratios have been calculated for five galaxy clusters (A1185, A1656, A2151, A2152, and A2197). A significant increase in the faint end slope between the inner (0.0-0.75 Mpc) and outer (0.75-1.50 Mpc) luminosity function is measured for A2151 (Ho = 50 km/s/Mpc). All five clusters show a significant dip in the luminosity function at MR = -19.5.
