The cluster galaxy luminosity function at z = 0.3: a recent origin for the faint-end upturn?

HARSONO D. and DE PROPRIS R.

Abstract (from CDS):

We derive deep luminosity functions (LFs) (to Mz= -15) for galaxies in Abell 1835 (z = 0.25) and AC 114 (z = 0.31), and compare these with the local z' LF for 69 clusters. The data show that the faint-end upturn, the excess of galaxies above a single Schechter function at Mz< -17, does not exist in the higher redshift clusters. This suggests that the faint-end upturn galaxies have been created recently, by infall into clusters of star-forming field populations or via tidal disruption of brighter objects.
