Description 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.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
