Abstract | The South Pole Telescope (SPT) has recently reported the first opticallyconfirmed clusters discovered via the SZ effect. In addition, SPT has detecteddozens more sources believed to be high redshift, 0.5 < z < 1.0, massiveclusters. We propose to use XMM-Newton to make observations of six of thebrightest clusters detected by the SPT. Follow-up observations of these clustersvia X-rays is essential in understanding the selection function of the survey bylinking the SZ observed flux to mass using the assumption of hydrostaticequilibrium and the X-ray temperature. A detailed comparison of the X-ray and SZobservations will also tell us much about the physics and evolution of thesepreviously undiscovered SZ effect selected clusters. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
