| Description | In the standard cosmological scenario of hierachical structure formation, bound objects are formed from the collapse of intial density fluctuations that grow under the influence of gravity. Clusters of galaxies are still forming today, at a rate that depends on the mean density of the Universe. We propose an XMM survey of the SHARC sample, a new catalogue of X-ray selected distant galaxy clusters (z > 0.2), detected in the ROSAT PSPC pointing archive. We will study the statistical properties of the evolving cluster population - e.g., the mass distribution function N(M,z) and correlations between physical quantities at various redshifts. This will provide unique |

| 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. |
