|Title||Baryons and Dark Matter in Hubble Treasury Clusters|
|Author||Dr Stefano Ettori|
|Description||The distribution of dark matter, baryons, and stars in a cluster gravitational potential is a fundamental prediction of models of large scale structure formation. We have been awarded 524 orbits of HST imaging to combine with Subaru and VLT data to measure the strong and weak lensing properties of 20 relaxed and 5 high-magnification galaxy clusters (z = 0.18 a?? 0.90, Tgas > 5 keV). Observing 8 clusters lacking XMM-Newton data will permit uniform joint X-ray-lensing-SZ analysis for 20 of these systems for a giant advance in our understanding of the shapes and concentrations of the mass profile, 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.
