The galaxy population of intermediate-redshift clusters.
DAHLEN T., FRANSSON C., OSTLIN G. and NASLUND M.
Abstract (from CDS):
Compared to low-redshift clusters, we find that a general fading of the late-type population by ∼2 mag and the early-type population by ∼1 mag describes the evolution from z= 0.55 to z= 0 well. As a consequence of the different early-type and late-type LFs and their dependence on cluster radius, the fraction of blue cluster galaxies, as measured by the Butcher-Oemler effect, differs between the clusters and depends on limiting magnitude and radius. We find a correlation between the dwarf-to-giant ratio and the surface density, indicating that the high-density environment in the cluster cores is hostile to dwarf galaxies.
