|Title||THE STRUCTURE AND EVOLUTION OF GALAXY GROUPS|
|Author||Prof TREVOR PONMAN|
|Description||We propose to conduct the first detailed, high quality survey of the X-ray and optical properties of a statistical sample of galaxy groups selected from the 2dF survey, using XMM in combination with the IMACS imaging spectrograph. The resulting dataset will probe the hot IGM down to the lowest fluxes observed in groups to date, and the galaxy luminosity function and dynamics down into the dwarf regime. The resulting dataset will provide a unique resource for studying the structure and evolution of groups, and the way in which group galaxies interact with their evolving environment. In the present pilot study, we target 6 of our sample of 25 groups, which span a wide range in group properties, and will launch our joint X-ray-optical study.|

|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.
