|A combined X-ray and SZ study of the growth of cosmic structure
|Dr Karl Andersson
|We propose to study the growth of cosmic structure by completing X-ray observations of the 20 z&amp;gt;0.7 clusters discovered in the first 600d of the SPT cluster survey. This proposal requests 545 ksec for 9 clusters with measured redshifts 0.7&amp;lt;z&amp;lt;1.1 and M500&amp;gt;3x10^14 M_sun. These observations are a critical part of a multi-wavelength campaign to calibrate SZE selected cluster masses using X-ray, weak lensing and velocity dispersions. In addition, the X-ray observations will directly constrain properties of clusters at zvirgul1, including the metallicity of the ICM, the cool core fraction, and the deviations from self-similar evolution at high redshift. When combined with WMAP 7-year results and the SPT survey, the X-ray mass calibration will allow a 6% constraint on w, the dark energy equation of state parameter.

|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.
