Description The goal of our project is to quantify the number of massive, high--redshift galaxy clusters, with the aim of constraining the density parameter of the Universe by employing the extreme sensitivity of the high--mass end of the cosmological mass function to Omega . For that purpose, we propose a two-fold aproach: 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--ray emission associated with more distant cluster candidates ( z>1 ) thought to be relatively massive due to either their lensing effects or their Sunyaev--Zel.dovich signal. This proposal is a collaboration between EPIC, SOC and SSC. OM filters to be changed if UHB limits updated.

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.
