Description We propose to observe two extraordinary, high-redshift galaxy clusters from the Massive Cluster Survey (MACS). These targets have been selected as two of the best examples of major mergers in the MACS catalogue, with clear evidence for considerable offset between the hot X-ray emitting gas and optically luminous stellar material. Subaru and Hubble Space Telescope optical data for these systems have been gathered by us and will be used to carry out gravitational lensing reconstructions of the total cluster masses. XMM X-ray data will be used to probe the mass distribution of hot, baryonic gas, and produce detailed maps of its thermodynamic state. The combination of these two mass measurements will be used to constrain the properties of dark matter in these objects.

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.
