Obscuring outflows are remarkably different from the common warm-absorberoutflows in AGN. They exhibit large columns of high-velocity gas closeto the black hole. They shield much of the X-ray radiation, which canhave important implications for the surrounding gas and the launching ofoutflows. Joint ToO observations with NuSTAR and XMM, triggered usingSwift monitoring, have been instrumental for the new results on obscurationevents to come into light. We request a ToO NuSTARobservation (50 ks) to be taken jointly with a XMM-Newton observation (50ks), using weekly Swift monitoring of an AGN sample (93 ks in total).

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.
