Description The near real-time comparison of XMM-Newton slew data with the ROSAT all-sky survey gives an excellent opportunity to find black holes in the centres of galaxies, which are currently being fueled by the tidal disruption of a star. The intensive study of such systems, where the boundary conditions, i.e. the recent history of the nuclear radiation, are known, can provide sensitive diagnostics in several areas of the AGN phenomenon. We propose to follow the dynamical evolution of the accretion process by studying the X-ray, UV and optical emission with regular observations. In AO9, this program was triggered on SDSS~J120136.02+300305.5, which has worked as a proof of concept. More events will allow the evolution to be followed for systems with different SMBH masses and stellar progenitors.

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.
