Description It now seems that the morphology-density relation is established by processes operating within groups, and only subsequently incorporated into clusters. The recent discovery that the HI-deficiency observed in galaxies within compact groups is related to the presence of a hot intergalactic medium, offers a clue to the processes involved in the transformation of the galaxy population. We propose to image a set of HI-deficient groups with XMM and Chandra, to compare the X-ray morphology with the HI distribution mapped by the VLA. This will enable us to discriminate between ram pressure stripping, tidal stripping and starburst mechanisms for the removal of gas from galaxies.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
