The near real-time comparison of XMM-Newton slew data with the ROSAT all-skysurvey gives an excellent opportunity to find black holes in the centres ofgalaxies, which are currently being fueled by the tidal disruption of a star.The intensive study of such systems, where the boundary conditions, i.e. therecent history of the nuclear radiation, are known, can provide sensitivediagnostics in several areas of the AGN phenomenon. We propose to follow thedynamical evolution of the accretion process by studying the X-ray, UV andoptical emission with regular observations. In AO9, this program was triggeredon SDSSvirgulJ120136.02+300305.5, which has worked as a proof of concept. More eventswill allow the evolution to be followed for systems with different SMBH masses and stellar progenitors.

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.
