| Description | Every major modern hydrodynamical simulation suite now includes a prescription for AGN feedback to reproduce realistic populations of galaxies. However, these simulations generally do not offer much insight into the nature of feedback. On the other hand, the hot gas content of galaxy groups is highly sensitive to the implemented feedback scheme: the predicted gas fraction differs by an order of magnitude from one simulation to another. Here we propose to observe a sample of 40 galaxy groups exhibiting X-ray emission on scales >12, with the aim of providing benchmark thermodynamic and gas fraction profiles out to R500 without requiring any extrapolation. The proposed program will gather a well controlled sample of systems spanning an order of magnitude in mass 1e13 < M500 < 1e14 Mo. |

| 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. |
