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. In June 2010, as part of this program, we detected a flare from the optically quiescent galaxy SDSS J120136.02+300305.5 and monitored its evolution. The source flux decays at the rate predicted for returning tidal debris but with surprisingly strong variations. A factor 50 flux reduction seen after 30 days, could be due to absorption by a super-Eddington outflow or may be caused by jet instabilities. We propose to extend this program to find and monitor more candidates and ultimately produce a small sample which can address the physics of tidal disruption events.

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.
