Description 2MASS 0918+2117 is a type 1.5 QSO at z=0.149. It was found to be unobscured in 2000 by Chandra, obscured by Compton Thick material in 2003 by XMM and unobscured again by XMM in 2005, when there is evidence (at 3sigma) of an absorption feature at 7 keV, indicating a disk wind with velocity of vout=0.13c, with poorly constrained physical parameters. A faster wind (vout=0.3-0.4c) may be present at 10 keV, at the limit of the XMM response. These evidences suggest that the source was caught in an obscuration and following blow-out phase, in which powerful AGN-driven winds sweep away the obscuring material around the SMBH. We propose to observe the source for 60ks with Nustar (plus 50ks XMM) to fully characterize the wind at all energies, or study the absorber if the obscuration is recurrent.

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.
