| Abstract | We propose a first-look survey of twelve galaxy clusters that, based on opticalselection criteria and archival X-ray data of similarly selected clusters, arevery likely to be bimodal merging clusters capable of constraining dark matterproperties. The candidates have $ge2sigma$ RASS excesses but otherwise havenot been studied with X-rays. By locating the X-ray peak(s) well enough todetermine if they have separated from the galaxies, the survey has the potentialto discover new laboratories to probe the nature of dark matter. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
