Supermassive black holes (BHs) residing in the brightest group/cluster galaxies(BGGs/BCGs) are over-massive relative to the stellar bulge mass of their hostgalaxy. In a pilot study, we demonstrated that these BHs do not correlate withthe stellar bulge mass of the BGG/BCG, but exhibit a surprisingly tightcorrelation with the total group/cluster mass. Thus, the evolution of these BHsis predominantly influenced by the large-scale properties of galaxygroups/clusters. This proposal aims to expand the sample with 7 galaxygroups/clusters. Based on the larger sample we will connect the total mass ofgroups/clusters with the BH mass of BGGs/BCGs.

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.
