|Title||Cosmology from X-ray and Weak Lensing Observations of SZ Discovered Clusters|
|Author||Dr Bradford Benson|
|Description||We propose to complete X-ray observations of a sample of 20 intermediate redshift (0.3 < z < 0.5) massive clusters of galaxies discovered via the Sunyaev-Zel.dovich (SZ) effect by the South Pole Telescope (SPT). These clusters are uniformly selected by their SZ significance from 560 deg2 surveyed by the SPT, and are part of a ground-based weak lensing program using Magellan. The combined observations will calibrate X-ray and SZ observables to the lensing mass estimates with an overall 5% uncertainty for the ensemble of clusters. This result will improve SPT cluster mass estimates, which when applied to the 2500 deg ^2 SPT survey will allow a 5% constraint on the dark energy equation of state. To complete this sample, we need observations of 6 clusters requiring a total of 93 ksec.|

|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.
