| Abstract | We propose to extend a program, running since AO-7, designed to find tidaldisruption events at the peak of their emission by a near-real time comparisonof XMM-Newton slew data with the ROSAT all-sky survey. Candidate events will bemonitored with XMM-Newton and Swift pointed observations, as well as spacedoptical spectra, to follow their temporal and spectral evolution. During thisprogram we have discovered and monitored flares from two optically quiescentgalaxies, SDSS J120136.02+300305.5 and 2MASX 07400785-8539307 and been able toshow, that their peak X-ray emission is reprocessed and not simply thehigh-energy tail of thermal emission as previously thought. |

| 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. |
