Description We propose to observe five cool clusters, in order to complete a flux-limited sample that does not suffer from optical selection bias. Cool clusters are excellent probes for understanding the heat balance in all clusters since their smaller potentials mean that they are most susceptible to heating processes. We aim to study, systematically, heating and cooling effects; together with the dispersion in the luminosity - temperature relation at temperatures below 2 keV (i.e. the intrinsic scatter in cluster properties). We have already made considerable progress analyzing the existing archived observations, and request additional observations to complete the sample. With its greater collecting area and low-energy response, XMM-Newton is the observatory of choice for this work.

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.
