XMM-Newton Proposal 02039804
Abstract
In almost all relaxed clusters, the X-ray emission is centred on a bright galaxy. However, from the most extensive study of cluster morphology available, based on Einstein data, we find a small class of clusters (just 2%) for which this is not the case. These clusters offer the best opportunity to study important but elusive phenomena which follow the disturbance of a cluster by a merger event (eg. shock compression, galactic wakes). The rarerity of these objects reflects that these phenomena are short-lived (for comparison, the shock compression period lasts less than 1Gyr). We propose to image such clusters with EPIC in order to discriminate between several interesting possible explanations for their aberrant morphology.
