XMM observation of cool clusters: the role of galaxy feedback

We propose to do high throughput spatialy resolved spectroscopy, with XMM, on a sample of 4 cool clusters (T 23 keV) in the redshift range z0.040.06. 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. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
