|Title||Preheating and the lowest temperature galaxy groups|
|Author||Mr Edward Lloyd-Davies|
|Description||The lowest temperature galaxy groups are of special interest, since in these systems the energy injection from galaxy winds has the most extreme effect. They also contain a large fraction of the baryons in the universe, due to their high space density. However their low X-ray surface brightness has made them the least observed and most poorly understood class of galaxy systems. XMM, with its large effective area presents the first chance to study these systems in detail. We propose to study three of the lowest temperature galaxy groups known in order to determine their structure, and the amount and source of energy injection which has profoundly affected them. We also intend to study the amount hot gas in these systems and so quantify their contribution to the global baryon budget.|

|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.
