Title: IFU mapping of the most energetic BALQSO outflows

Abstract: We propose to obtain the first spatial maps of Broad Absorption Line (BAL) quasar outflows, which will also spatially probe an order of magnitude faster AGN outflows than previously done. Our VLT UVES and X-Shooter programs showed that BAL outflows can carry enough kinetic luminosity to be the major agent of AGN feedback. This was done by determining the outflow's galactocentric distance and the total column density towards the quasar. However, the geometry of the outflowing gas around the quasar cannot be obtained from such data but has to be assumed from statistical arguments. We propose GMOS IFU observations of 2 of the most energetic quasar outflows we found at z=0.6-0.7, which have extents of 6-7 kpc as per our published BAL analyses. These observations will yield the plane-of-the-sky outflow geometry, and thus eliminate the last uncertainty in measuring their energetics. The combination of absorption and IFU data promises to lead to a significant leap for investigating the role of quasar outflows in galaxy formation.
