| Abstract | X-ray observations of galaxy groups currently give the best evidence thatnon-gravitational processes cause departures from self-similarity. There aremany types of groups, possibly related to different evolutionary states;spiral-dominated compact groups have been neglected in X-ray studies untilrecently. We propose to observe three spiral-rich HCGss with XMM in order to:(i) test whether such groups constitute a subclass of groups with specific X-raycharacteristics, or whether their properties are simple extrapolations of thoseof elliptical-dominated groups; (ii) check the pre-heating scenario and comparedifferent sources for this energy and entropy input; (iii) explore the relationbetween galaxy activity and intragroup gas enrichment. |

| 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. |
