Abstract The goal of our project is to quantify the number of massive, high-redshiftgalaxy clusters, with the aim of constraining the density parameter of theUniverse by employing the extreme sensitivity of the high-mass end of thecosmological mass function to Omega. For that purpose, we propose a two-foldapproach: 1) measure the temperature of a sample of known high-z (0.4<z<0.7)clusters detected in the SHARC X-ray survey, and 2) search for the X-rayemission associated with more distant cluster candidates (z>1) thought to berelatively massive due to either their lensing effects or theirSunyaev-Zeldovich signal.NOTE: Soc enhance request: pn/filter might need to be changed if optical loading proves not to be a problem for pn/CTI

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.
