| Description | We propose to observe with XMM a small sample of galaxy clusters to obtain temperature maps with good precision. Our sample consists of clusters that have SZE images, weak and/or strong gravitational lensing maps, and are bright X-ray sources. The combination of lensing, X-ray, and SZE data will allow us to measure the Hubble constant, derive a model-independent value for the baryon fraction, and test common assumptions in estimating cluster dark matter, including hydrostatic equilibrium, spherical symmetry, and minimal substructure. |

| 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. |
