| Description | Galaxy clusters have proven to be highly competitive and complementary cosmological probes. For the next major breakthrough more reliable mass estimates and, therefore, a better understanding of cluster physics are essential. We propose to complete XMM-Newton observations of a flux-limited sample of the 64 X-ray brightest clusters in the sky to (i) take full advantage of 3 Ms of XMM-Newton data already available, (ii) determine very precise gas temperature profiles, (iii) characterize merging clusters by direct comparison to simulations, (iv) update the luminosity-mass relation, (v) construct the most precise local cluster mass function, (vi) improve constraints on OmegaM and sigma8 significantly, and (vii) provide a reliable statistical baseline for comparison to high-redshift samples. |

| 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. |
