Scientific paper

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.
