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. [truncated! Please see actual data for full text]
