Abstract	Galaxy groups are ideal systems to study baryon physics, which is important forboth using clusters for precision cosmology and understanding galaxy formationand evolution. Over the last decade, our understanding on the ICM properties ofgalaxy groups has been greatly improved. However, there is no a representativegroup sample with Chandra or XMM that allows full coverage to r_500. We definedsuch a sample of 13 galaxy groups that are X-ray luminosity selected from the400 deg^2 survey (REGOS4). The low-L_X bin was approved in the last XMM cycle.Complete Chandra coverage (mostly short exposures) and other supporting datahave also been obtained. We now propose to observe the high-L_X bin with XMM tofinish REGOS4 and ensure a continuous L_X coverage from REXCESS to REGOS4.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
