| Abstract | Galaxy groups are the most common bound galaxy systems, and unlike clusters, themetal enrichment of their environments can be heavily dominated by galacticwinds. The potential well of groups is too shallow to hold protogalactic winds,so that intragroup medium (IGM) should be mostly enriched by secondary SNIawinds. This enrichment history should be evident in the relative metal abundanceratios. We propose to measure the enrichment properties in 2 typical galaxygroups determine the IGM contamination from SNIa & II and study in detail SNIawind energetics, testing whether SN II winds escaped completely from the HCGsor if they were trapped,by massive DM halos. |

| 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. |
