Scientific paper

We propose a fully-sampled mosaic of 41 ACS images to survey galaxy morphologies and measure weak lensing signals to the turn-around radius in the X-ray luminous cluster, MS0451-03 {z=0.54}. The aim is to isolate the physical processes which affect the evolution of cluster galaxy morphologies in the context of well-defined dynamical system. The study will be used in contrast to a successful campaign undertaken in Cycle 9 on a optically-selected target. By comparing morphologies with spectroscopic and Chandra X-ray data, we will quantify the role of the intracluster medium and associated substructures and establish the timescales and physical regions within which the various environmental processes occur.
