Abstract We propose to use the Advanced Camera for Surveys to image four selected fields in the outskirts of the rich, X-ray luminous cluster MS1054-03 at z=0.83. The high- resolution and sensitivity of ACS is required in order to study the properties of the population of galaxies falling into the cluster for the first time. By targeting regions of the cluster well beyond the virial radius, we will: (1) study the transformation of infalling field spirals into cluster early-types using, e.g., the morphology-density relation to large radii and very low local densities; (2) determine the star-formation histories of those field galaxies most recently accreted by the cluster, using accurate colors, morphologies, bulge-to- disk ratios, bulge and disk scale lengths, M/L ratios and line strengths; and (3) measure the frequency of galaxy-galaxy mergers and interactions in the infall region. By combining wide-field HST/ACS data with wide-field multi-object spectroscopy from the Magellan and Keck telescopes, we can test the predictions made by galaxy formation models, study how field spirals become early-type cluster members, and better constrain the formation and evolution of galaxies in both clusters and the field. ------------------------------------------------------------------------------------ 9772( 5) - 09/17/03 11:03 - [ 2] Observations Description ------------------------ ACS/WFC two-color imaging in the outskirts of a cluster of galaxies at z=0.83. The orientation is fixed to that of the GTO data in the core of the cluster, in order to ensure small overlap regions and a contiguous field-of-view. A three- point line pattern is used to cover the gap and ensure that hot pixels and cosmic-rays can be elliminated, while minimizing the overhead of extra reads.
