|Title||Cosmological Constraints from X-ray Observations of SZ Discovered Clusters|
|Author||Dr Bradford Benson|
|Description||We propose to observe 14 intermediate redshift massive clusters of galaxies discovered via the Sunyaev-Zel.dovich (SZ) effect by the South Pole Telescope (SPT). Currently the SPT survey has measured redshifts for 194 clusters, the majority of which are newly discovered clusters at z > 0.5. We propose to observe a sub-sample of SPT clusters at redshifts between 0.3 < z < 0.5 to obtain well calibrated Yx-derived mass estimates. With these mass estimates and the WMAP 7-year results, we expect that the SPT survey will allow a 7% constraint on "w", the dark energy equation of state, a factor of 2 improvement over comparable constraints using cluster evolution and WMAP from Vikhlinin et al.(2009).|

|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.
