Description At present, the only group known to be in the process of converting cold gas into a hot X-ray emitting intra-group medium and thus starving star-formation in its member galaxies is Stephan.s Quintet. The NGC 5903- NGC 5898 group may be the second example. It contains a 100kpc HI filament and a 65kpc diameter diffuse radio structure which appear to be anti-correlated. A bright ridge in the radio structure may be a shock driven by a galaxy-HI collision, as in Stephan.s Quintet. Alternatively the radio emission may be a remnant of old AGN activity, but in either case the group should be X-ray luminous. A short (50ks) XMM observation will allow us to discriminate between the two scenarios, and examine how groups form and maintain their hot intra-group medium.

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.
