|Title||Deep X-ray Spectroscopy of the Most Distant, Massive Clusters Known|
|Author||Dr Esra Bulbul|
|Description||We propose to observe the six most massive clusters at z>1.2, discovered via the Sunyaev-Zel.dovich (SZ) effect by the South Pole Telescope (SPT). The proposed 700 ks program will provide deep X-ray spectroscopy for a sample that is already rich in multi-wavelength data from a variety of telescopes, including Spitzer, Hubble, and Chandra. These new data, coupled with spatially-resolved X-ray imaging from Chandra, will provide the first constraints on the thermodynamic profiles for a complete sample of galaxy clusters at z>1.2, allowing us to study a variety of physical processes in clusters cores and outskirts, and test predictions of self similarity and AGN feedback models, at a time shortly after these systems formed.|

|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.
