Description We propose X-ray observations of three X-ray bright ..fossil groups. centered
on the dominant galaxies NGC4936, IC1633 and NGC6269. With XMM-Newton, we can
derive accurate gas density, temperature, abundance, pressure, and entropy
distributions to test mass distribution predictions from numerical simulations,
investigate the interaction of radio lobes with the cooling gas in the central
galaxies, determine the past star formation history, inventory the stellar
component through abundance determinations, test formation theories of fossil
groups to determine their relationship to more typical groups and clusters, and
finally, test models of thermal conduction which may explain the absence of cool
gas in ..cooling flows..

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.
