The Narrow Line Region in 3D: mapping AGN feeding and feedback
  Early studies of nearby Seyfert galaxies have led to the picture that the
Narrow Line Region (NLR) is a cone-shaped region of gas ionized by radiation
from a nuclear source collimated by a dusty torus, where the gas is in outflow.
In this contribution, I discuss a 3D view of the NLR obtained via Integral
Field Spectroscopy, showing that: (1) although the region of highest emission
is elongated (and in some cases cone-shaped), there is also lower level
emission beyond the "ionization cone", indicating that the AGN radiation leaks
through the torus; (2) besides outflows, the gas kinematics include also
rotation in the galaxy plane and inflows; (3) in many cases the outflows are
compact and restricted to the inner few 100pc; we argue that these may be early
stages of an outflow that will evolve to an open-ended, cone-like one. Inflows
are observed in ionized gas in LINERs, and in warm molecular gas in more
luminous AGN, being usually found on hundred of pc scales. Mass outflow rates
in ionized gas are of the order of a few solar masses per year, while the mass
inflow rates are of the order of tenths of solar masses per year. Mass inflow
rates in warm molecular gas are ~4-5 orders of magnitude lower, but these
inflows seem to be only tracers of more massive inflows in cold molecular gas
that should be observable at mm wavelengths.
