Description We aim at exploiting the high-quality X-ray spectroscopy and broad-band spectral coverage of XMM and NuSTAR to reveal the physics, structure and location of the X-ray obscuring matter in Seyferts. We request a simultaneous monitoring with XMM and NuSTAR of Mrk915, a local, X-ray bright and obscured AGN where a significant variation in the NH (Delta NHvirgul10^23cm-2) has been revealed by short exposure Swift data. We ask for a long observation (130ks) with XMM followed by 2 shorter (50ks each) at a distance of about 4 and 10 days from the first one, combined with 3 observations with NuSTAR of 50ks each, to be performed simultaneously to XMM. This will allow us to probe variability on timescales from <2 days (in the 130ks observation) to 10 days, placing strong constraints on the absorber structure.

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.
