| Abstract | We propose to do high throughput spatialy resolved spectroscopy, with XMM, on a sample of 4 cool clusters (T = 2-3 keV) in the redshift range z=0.04-0.06. XMM/EPIC is the best instrument to measure the temperature and abundance profiles in these objects, up to large radii from the center. We will thus be able to estimate accuratly the gas entropy distribution, the relative distribution of the gas and the dark matter, the abundance of Iron and alpha elements and their gradients. These are the key constrains on the chemical and thermodynamical history of the gas. This will allow a major step forward in our understanding of the role of galaxy feedback in cluster evolution. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
