Description
We describe the HST ACS Coma Cluster Treasury survey, a deep
two-passband imaging survey of one of the nearest rich clusters of
galaxies, the Coma Cluster (Abell 1656). The survey was designed to
cover an area of 740 arcmin2 in regions of different density
of both galaxies and intergalactic medium within the cluster. The ACS
failure of 2007 January 27 leaves the survey 28% complete, with 21 ACS
pointings (230 arcmin2) complete, and partial data for a
further four pointings (44 arcmin2). The predicted survey
depth for 10 σ detections for optimal photometry of point sources
is g'=27.6 in the F475W filter and IC=26.8 mag in
F814 (AB magnitudes). Initial simulations with artificially injected
point sources show 90% recovered at magnitude limits of
g'=27.55 and IC=26.65. For extended sources, the
predicted 10 σ limits for a 1 arcsec2 region are
g'=25.8 mag arcsec-2 and IC=25.0 mag
arcsec-2. We highlight several motivating science goals of
the survey, including study of the faint end of the cluster galaxy
luminosity function, structural parameters of dwarf galaxies, stellar
populations and their effect on colors and color gradients, evolution of
morphological components in a dense environment, the nature of
ultracompact dwarf galaxies, and globular cluster populations of cluster
galaxies of a range of luminosities and types. This survey will also
provide a local rich cluster benchmark for various well-known global
scaling relations and explore new relations pertaining to the nuclear
properties of galaxies.
Based on observations with the NASA/ESA Hubble Space Telescope obtained
at the Space Telescope Science Institute, which is operated by the
association of Universities for Research in Astronomy, Inc., under NASA
contract NAS5-26555. These observations are associated with program
GO10861.

Galaxy Evolution in Clusters of Galaxies
Galaxies in the universe can be located in different environments, some of them are isolated or in low density regions and they are usually called field galaxies. The others can be located in galaxy associations, going from loose groups to clusters or even superclusters of galaxies. One of the foremost challenges of the modern Astrophysics is to
