We use deep adaptive optics assisted integral field spectroscopy from SINFONI
on the VLT to study the spatially resolved properties of ionized gas outflows
driven by active galactic nuclei (AGN) in three galaxies at z~2.2 — K20-ID5,
COS4-11337 and J0901+1814. These systems probe AGN feedback from nuclear to
circumgalactic scales, and provide unique insights into the different
mechanisms by which AGN-driven outflows interact with their host galaxies.
K20-ID5 and COS4-11337 are compact star forming galaxies with powerful
$sim$1500 km s$^{-1}$ AGN-driven outflows that dominate their nuclear
H$alpha$ emission. The outflows do not appear to have any impact on the
instantaneous star formation activity of the host galaxies, but they carry a
significant amount of kinetic energy which could heat the halo gas and
potentially lead to a reduction in the rate of cold gas accretion onto the
galaxies. The outflow from COS4-11337 is propagating directly towards its
companion galaxy COS4-11363, at a projected separation of 5.4 kpc. COS4-11363
shows signs of shock excitation and recent truncation of star formation
activity, which could plausibly have been induced by the outflow from
COS4-11337. J0901+1814 is gravitationally lensed, giving us a unique view of a
compact (R = 470 $pm$ 70 pc), relatively low velocity ($sim$650 km s$^{-1}$)
AGN-driven outflow. J0901+1814 has a similar AGN luminosity to COS4-11337,
suggesting that the difference in outflow properties is not related to the
current AGN luminosity, and may instead reflect a difference in the
evolutionary stage of the outflow and/or the coupling efficiency between the
AGN ionizing radiation field and the gas in the nuclear regions.
