We propose to observe 8 galaxy groups with a total exposure time of 68 ks tocomplete observations for a flux limited sample consisting of 67 objects. Wewill use this well-defined sample to study the scaling law properties of locallow-mass systems. Only with the requested observations we will be able tocorrect for sample selection effects entering in the scaling relations,increasing the constraining power by a factor of 2 compared to previous samples.Furthermore, we will determine detailed thermodynamic profiles within R2500(i.e., the region where simulations differs more noticeably) putting constraintson the feedback processes.

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.
