Kiloparsec-scale outflows are prevalent among luminous AGN: outflows and
  feedback in the context of the overall AGN population
  We present integral field unit (IFU) observations covering the [O
III]4959,5007 and H-Beta emission lines of sixteen z<0.2 type 2 active galactic
nuclei (AGN). Our targets are selected from a well-constrained parent sample of
24,000 AGN so that we can place our observations into the context of the
overall AGN population. Our targets are radio-quiet with star formation rates
(<~[10-100] Msol/yr) that are consistent with normal star-forming galaxies. We
decouple the kinematics of galaxy dynamics and mergers from outflows. We find
high-velocity ionised gas (velocity widths of 600-1500 km/s and maximum
velocities of <=1700 km/s) with observed spatial extents of >~(6-16) kpc in all
targets and observe signatures of spherical outflows and bi-polar superbubbles.
We show that our targets are representative of z<0.2, luminous (i.e., L([O
III]) > 5x10^41 erg/s) type 2 AGN and that ionised outflows are not only common
but also in >=70% (3 sigma confidence) of cases, they are extended over
kiloparsec scales. Our study demonstrates that galaxy-wide energetic outflows
are not confined to the most extreme star-forming galaxies or radio-luminous
AGN; however, there may be a higher incidence of the most extreme outflow
velocities in quasars hosted in ultra-luminous infrared galaxies. Both star
formation and AGN activity appear to be energetically viable to drive the
outflows and we find no definitive evidence that favours one process over the
other. Although highly uncertain, we derive mass outflow rates (typically ~10x
the SFRs), kinetic energies (~0.5-10% of L[AGN]) and momentum rates (typically
>~10-20x L[AGN]/c) consistent with theoretical models that predict AGN-driven
outflows play a significant role in shaping the evolution of galaxies.
