Description We propose to extend a program, running since AO-7, designed to find tidal
disruption events at the peak of their emission by a near-real time comparison
of XMM-Newton slew data with the ROSAT all-sky survey. Candidate events will be
monitored with XMM-Newton and Swift pointed observations, as well as spaced
optical spectra, to follow their temporal and spectral evolution. During this
program we have discovered and monitored flares from two optically quiescent
galaxies, SDSS J120136.02+300305.5 and 2MASX 07400785-8539307 and been able to
show, that their peak X-ray emission is reprocessed and not simply the
high-energy tail of thermal emission as previously thought.

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.
