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

| 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. |
