We propose to observe the X-ray cavity cluster RBS797, in which radio emissionis seen on three different scales and orientations and a massive starburst isfound at its center. With the requested observation we aim to: 1) determine theglobal properties of the cluster (temperature, mass, luminosity) and assess itsconformity to scaling relations in order to investigate the potential impact ofAGN feedback; 2) compare cooling rate or limits with the star formation rate; 3)investigate the nature of the large-scale radio emission by using the X-rayproperties as input to test the electron reacceleration model for the origin ofradio mini-halos; 4) study the ICM enrichment process by means of a metallicitymap.

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.
