Description IGR 12580+0134 is one of rare TDEs found with off-beam relativistic jet, and is by far the nearest TDE ever found (dvirgul17Mpc). The source presented extremely unusual evolution of X-ray lightcurve, with a rapid flux drop at virgul600 days followed by a weak but nearly constant X-ray emission that was visible at least until virgul2600 days after the stellar capture. This cannot be explained by standard tidal disruption theories, but may be a Compton echo effect resulting from the Thomson scattering between primary X-rays and its surrounding gas. The goal of XMM proposal is to obtain high quality X-ray spectrum to test the Compton echo scenario for interpreting the residual X-ray emission. If confirmed, the observation will enable to constrain the size, density and geometry of the surrounding gas to BH.

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.
