Feeding Versus Feedback in AGN from Near-Infrared IFU Observations XI:
  NGC 2110
  We present a two-dimensional mapping of the gas flux distributions, as well
as of the gas and stellar kinematics in the inner 220 pc of the Seyfert galaxy
NGC 2110, using K-band integral field spectroscopy obtained with the Gemini
NIFS at a spatial resolution of ~24pc and spectral resolution of ~40 km/s. The
H2 emission extends over the whole field-of-view and is attributed to heating
by X-rays from the AGN and/or by shocks, while the Brgamma emission is
restricted to a bi-polar region extending along the South-East-North-West
direction. The masses of the warm molecular gas and of the ionized gas are
~1.4x10^3 Msun and ~1.8x10^6 Msun, respectively. The stellar kinematics present
velocity dispersions reaching 250km/s and a rotation pattern reaching an
amplitude of 200 km/s. The gas velocity fields present a similar rotation
pattern but also additional components that we attribute to inflows and
outflows most clearly observed in the molecular gas emission. The inflows are
observed beyond the inner 70 pc and are associated to a spiral arm seen in
blueshift to the North-East and another in redshift to the South-West. We have
estimated a mass inflow rate in warm molecular gas of ~4.6x10^-4 Msun/year.
Within the inner 70 pc, another kinematic component is observed in the H2
emission that can be interpreted as due to a bipolar nuclear outflow oriented
along the East-West direction, with a mass-outflow rate of ~4.3x10^-4 Msun/year
in warm H2.
