Description We propose an XMM-Newton survey of 10 nearby groups from the representative flux
limited NORAS sample. Our proposed sample spans the range of X-ray luminosities
(and thus temperatures) for groups. The high signal-to-noise data we obtain will
be used to derive entropy profiles from the very centers of these groups out to
approximately half of the virial radius. These entropy profiles will be used to
constrain the history of heating and cooling in groups. The XMM data will also
allow a detailed study of the abundance gradients of the hot gas in the elements
of Fe, O, Si and S, which will provide constraints on the stars responsible for
the enrichment. Finally, we will measure accurate mass and baryon profiles and
thus determine the contribution of groups to the mass density of 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.
