Description We propose to observe three normal, bright, (relatively) isolated elliptical galaxies that are surrounded by extended dark matter and hot gas halos typical of poor clusters, with spatial extents of 500-1000 kpc. These systems, selected from X-ray surveys, are probably fossil groups, systems whose bright galaxies have merged into a single bright galaxy. With XMM-Newton, we will derive accurate gas density and temperature profiles to test mass distribution predictions from numerical simulations, investigate any cooling gas in the centers, determine the star formation history, inventory the stellar component through the abundance determinations, and test formation theories of fossil groups to determine their relationship to more typical groups and clusters.

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.
