IGR 12580+0134 is one of rare TDEs found with off-beam relativistic jet comma and is by far the nearest TDE ever found openPardvirgul17MpcclosePar. The source presented extremely unusual evolution of X-ray lightcurve comma 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 comma 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 comma the observation will enable to constrain the size comma density and geometry of the surrounding gas to BH.
