Description Under very general theoretical assumptions, the evolution of the space density of clusters of galaxies is extremely sensitive to cosmological parameters. The most straightforward method of exploiting this sensitivity is through measurements of the X-ray temperature function. We propose to reobserve two clusters that were awarded time in previous XMM AOs but whose data were rendered unusable due to high background periods. These clusters are required to finish the statistically complete sample needed to measure the temperature function.

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.
