|Title||Reobservation of some Clusters of the XMM Legacy Program for Cluster Structure|
|Author||Prof Hans Boehringer|
|Description||To use clusters as sensitive probes to study the emergence of cosmic structure and to test cosmological models, we need a better knowledge of the scaling relations of cluster mass and observable properties. With this goal a Large Program was approved in AO3 to study a representative sample of 34 clusters in detail. The observations are now completed. While we obtained very good results for a large fraction of the clusters, a substantial fraction of the data are rendered unusable by high background events as demonstrated below. To achieve our observational goals, it is critical that the complete sample be observed and the clusters with the poorest data, 9 clusters, be reobserved. In addition, note that multi-wavelength observations of the entire sample have begun.|

|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.
