|Title||X-SORTER: X-ray Survey Of meRging clusTErs in Redmapper|
|Author||Prof David Wittman|
|Description||We propose a first-look survey of twelve galaxy clusters that, based on optical selection criteria and archival X-ray data of similarly selected clusters, are very likely to be bimodal merging clusters capable of constraining dark matter properties. The candidates have ge2sigma RASS excesses but otherwise have not been studied with X-rays. By locating the X-ray peak(s) well enough to determine if they have separated from the galaxies, the survey has the potential to discover new laboratories to probe the nature of dark matter.|

|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.
