Description We propose to complete the last 10% of high-quality observations for the eeHIFLUGCS galaxy cluster sample (36 of 376 clusters). The sample is based on ROSAT with completely and homogeneously redetermined fluxes as well as updated redshifts. For the already observed clusters we have also identified >10 double-triple clusters and clusters dominated by AGN emission, which then fall below the flux limit of 5e- 12 erg-s-cm2. With the completed follow-up observations we will decrease the uncertainties in OmegaM by a factor of 2.8 compared to those obtained with the HIFLUGCS sample. If these 10% do not get observed, the flux-limited sample drops by almost a factor of 3 to a disappointing 137 clusters. The observations will also have long lasting legacy value for a range of astrophysical studies

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.
