| Abstract | We propose the observation of two hyper-luminous extra-galactic sources withpossible quasi-periodic variability, belonging to a sample of ~40 super- softX-ray sources we recently discovered. The luminosity and temperature of theobjects in this sample is larger than 10^41 erg/s and around 60-100 eV,respectively, making them either Tidal Disruption Event candidates, orIntermediate Mass Black Hole candidates. We propose the observation of 2 of themost extreme sources for which we have a single observation showing hints ofshort-term variability. Our goal is to check their short-term light-curves forQPOs and their long-term one in order to confirm or exclude their TDE 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. |
