Scientific paper

Our current understanding of the X-ray properties of galaxy groups is limited by poor quality data and an inhomogeneous and non-representative coverage of the mass function. We propose to make deep observations of a representative, X-ray luminosity selected sample of 9 galaxy groups drawn from a complete flux-limited catalogue. We will measure the temperature out to R_500 with similar accuracy to that available for high quality observations of nearby clusters (e.g., REXCESS). We will investigate the relative importance of gravitational and non-gravitational processes in setting the observed X-ray properties of group scale haloes, via extensive examination of their structural and scaling properties.
