Cluster galaxies in XMMU J2235-2557: galaxy population properties in most massive environments at<i>z</i> ~ 1.4

Abstract

We present a multi-wavelength study of galaxy populations in the core of the massive, X-ray luminous cluster XMMU J2235 at z = 1.39, based on high quality VLT and HST photometry at optical and near-infrared wavelengths.
