Scientific paper

Wakes generated as galaxies move through hot intracluster gas are important in their own right, since stripping and accretion can have profound effects on galaxy evolution. Wakes also provide valuable diagnostics of galaxy properties and cluster dynamics. Previous X-ray observatories have been able to study only a small number of especially bright and nearby galaxy wakes. With Chandra, we have the possibility for the first time, of imaging a whole sample of wakes within a single cluster, allowing us to examine their properties and scaling relations. We have chosen two clusters with optimal temperatures and distances but strongly contrasting morphologies: A160 is a relaxed cluster, whilst A194 is currently merging. We expect to detect at least seven wakes in each system.
