| Abstract | We propose a simultaneous 240 ks XMM 120 ks NuSTAR observation to study theproperties of the disk wind detected in Mrk231. The nearby ULIRG/QSO Mrk231 isan exceptional QSO and a prototypical object, where we are viewing the feedbackin action with overwhelming evidence of multiphase outflows. Mrk231 is a BALQSO, where both a X-ray wind and galaxy-scale outflows were detected and appears to follow the prediction for an energy conserving scenario. Despitethat, the physical properties of the X-ray wind are poorly known. Our proposedobservation will be the first broad-band observation deep enough to properlyinvestigate this wind. This observation will allow us to put strongerconstraints on the energetics of the disk wind and test if it is one of the few energy conserving winds. |

| 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. |
