Abell 851 and the role of starbursts
Listed in IVOA Registry (Virtual Observatory)
We use extensive new observations of the very rich z~0.4 cluster of galaxies A851 (Cl 0939+47) to examine the nature and origin of starburst galaxies in intermediate-redshift clusters.
Description
New HST observations, 24um Spitzer photometry and ground-based spectroscopy cover most of a region of the cluster about 10' across, corresponding to a cluster-centric radial distance of about 1.6Mpc. This spatial coverage allows us to confirm the existence of a morphology-density relation within this cluster, and to identify several large, presumably infalling, subsystems.
We confirm our previous conclusion that a very large fraction of the star-forming galaxies in A851 has recently undergone starbursts. We argue that starbursts are mostly confined to two kinds of sites: infalling groups and the cluster center.
