| Abstract: |
I briefly highlight some recent results and ongoing work on galaxy clusters and superclusters using the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope (HST), with supporting ground-based data. These projects range from detailed investigations of the galaxy populations in clusters at redshift z ≈ 1, where we find highly evolved galaxies in young clusters, to the detailed 3-D structure of the Virgo cluster at z ≈ 0.004, which we find to be quite compact but accreting groups from the surrounding supercluster. In addition, we have a large HST program studying infall into the Shapley Supercluster region, in an effort to determine its influence on the Local Group motion. |
