Description We propose to complete our X-ray follow-up program aimed at observing the ACT Cosmological Sample of Clusters, which is a well-defined sample of 22 massive galaxy clusters detected by the Atacama Cosmology Telescope using the Sunyaev-Zel.dovich effect (SZE). There remain five newly-discovered SZE clusters in this sample without any X-ray data. The proposed XMM-Newton EPIC observations will provide accurate gas masses and temperatures to be used for a precision calibration of the SZE signal versus mass scaling law out to redshifts of 1. This effort is an essential part of our intensive multi-wavelength campaign to obtain mass measurements for the ACT Cosmological Sample of Clusters.

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.
