We propose to observe the X-ray cavity cluster RBS797, which has a massivecentral starburst and a unique radio source that exhibits large changes inorientation with scale. With the requested observation we aim at: 1) determiningthe global properties of the cluster (temperature, metallicity, mass, gas massfraction) up to virgul1.3 Mpc (virgul0.5 r_vir), and investigating the potential impact ofAGN feedback on scaling relations; 2) characterizing the AGN/ICM interaction byinvestigating the nature of the extended radio emission; 3) comparing thecooling rate or limits with the star formation rate.

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.
