Description Despite the importance of galaxy groups as the most common galaxy environment, and the likely repository of the majority of baryons in the Universe, no study of the dynamics and baryon contents of an unbiased sample has ever been conducted. We have begun a project to remedy this, targetting a sample of 25 groups derived from the 2dF galaxy redshift survey with XMM, in combination with the large IMACS imaging spectrograph. 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. Optical imaging and IMACS spectroscopy of these is progressing well, and we request 20 ksec observations of seven groups, to add to the three awarded in AO-3.

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.
