Description The distribution of dark matter, baryons, and stars in a cluster gravitational potential is a fundamental prediction of large-scale structure formation. We have 524 orbits of HST imaging together with Subaru and VLT spectroscopy to measure the strong and weak lensing properties of 20 relaxed and 5 high-magnification galaxy clusters (z = 0.18 - 0.90, Tgas > 5 keV). Observing the last 3 relaxed clusters with good visibility lacking XMM data will permit uniform joint Xray-lensing-SZ analysis for 17 of the relaxed systems to advance our understanding of the shapes and concentrations of the mass profiles, providing precise observational benchmarks for baryonic and dark matter distributions over a range of redshifts.

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.
