Description The main objective of this program is to test the possibility that a fossil group is the end-product of the merging of dense groups-poor clusters. Fossil groups exhibit an extended X-ray halo with LX, total mass and gas mass similar to poor clusters, but optically they are dominated by a single luminous elliptical galaxy surrounded by faint companions. We plan to obtain XMM-Newton data to analyse the diffuse emission of two fossils groups selected from the SDSS and ROSAT databases. We will determine their masses, M-L, measure their temperatures and metallicities and map their gas densities, in order to infer their dynamical states.

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.
