Title Confirming the nature of 5 tidal disruption event candidates

Description In a search for new TDEs candidates we cross-matched optical and x-rays catalogues. We propose the observation of 5 of our best candidates: these galaxies show a high x-rays luminosity (L_X>10^41 erg-sec) and an extremely soft spectrum (Gamma>3) in the same energy band. As no other known source should be able to show a similar behaviour we are positive that these are unrecognized TDEs. If these galaxies indeed hosted a TDE we expect that by now their luminosity should have dropped by a significant factor (>5) allowing us to confirm their nature.

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.
