Title: QSO Feedback in Action: The Inner Structure of a Large-Scale QSO Wind

Abstract: We have recently discovered the first unambiguous evidence for kiloparsec-scale QSO-mode feedback in a galaxy merger. GMOS/IFU observations of Mrk 231 have revealed a massive, wide-angle, kiloparsec- scale outflow that is clearly powered by the QSO and is removing large amounts of gas from the center of the galaxy at velocities exceeding 1000 km/s. Here, we propose to use NIFS with AO-LGS to map the warm ionized, warm molecular, and possible coronal phases of this wind at the highest possible spatial resolution. Such data will constrain the launching region and mechanism of the wind at 100 pc (0\farcs1) resolution, including its relationship to the classic narrow-line region. This proposal is part of a multiwavelength campaign to observe Mrk 231, including published Herschel and IRAM data and accepted HST/COS (5 orbits), Chandra (400 ks), and GBT observations. None of these ancillary data will constrain the wind structure at sub-arcsecond resolution, as the proposed AO observations will do.
