Abstract We propose to observe with XMM a small sample of galaxy clusters toobtain temperature maps with good precision. Our sample consists ofclusters that have SZE images, weak and/or strong gravitationallensing maps, and are bright X-ray sources. The combination oflensing, X-ray, and SZE data will allow us to measure the Hubbleconstant, derive a model-independent value for the baryon fraction,and test common assumptions in estimating cluster dark matter,including hydrostatic equilibrium, spherical symmetry, and minimalsubstructure.

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.
