Title Characterizing the nature of Fossil Groups with XMM

Description The low number of confirmed and well studied FGs has hampered so far the attempts to constrain the abundance and properties of these systems. The number of well studied FG is about 10, with only 7 temperature estimates; moreover they are spread over a large redshift range. Using SDSS and RASS data, we assembled one of the largest comprehensive and objective samples of FG candidates available in the literature. We propose to use XMM to confirm the nature of 12 optimally selected candidates, more than doubling the number of known FGs. Their X-ray properties will be compared to a sample of field ellipticals and to cosmological simulations, in order to understand if FGs represent the final evolutionary stage of galaxy groups or just the tip of the galaxy group distribution with peculiar LF.

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.
