Current models of galaxy evolution rely critically on AGN and SN feedbackprocesses. However, these ideas have not been fully tested, particularly in theintra-group medium (IGM), the environment most commonly experienced by galaxies.For this purpose we propose to use XMM-Newton to study the thermodynamicproperties of the IGM (via its diffuse X-ray emission), which retains a fossilrecord of the energy released by past star formation and AGN activity, for anunbiased sample of 23 groups with fully determined galaxy population and AGNproperties. The 23 target groups are selected from our Zurich ENvironmentalSurvey, for which we have optical spectroscopic, photometric and morphologicalinformation as well as HI mass content.

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.
