Description The high densities and low velocity dispersions seen in galaxy groups can lead to the formation of 'fossil groups., in which all the major galaxies have merged to form one giant elliptical. Very few of these objects have been observed, and almost all are at moderate redshift, making detailed analysis difficult. We have defined a sample of fossil candidates at low redshift, and propose to use XMM-Newton to characterise their X-ray halos. High resolution observations of these targets will allow us to test our understanding of their nature and origins, and to measure the properties of what may be the oldest undisturbed galaxy systems in the Universe.

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.
