Feeding and Feedback in NGC3081
  We present two-dimensional gaseous kinematics of the inner 1.2 $\times$ 1.8
kpc$^2$ of the Seyfert 2 galaxy NGC3081, from optical spectra (5600--7000\r{A})
obtained with the GMOS integral field spectrograph on the Gemini North
telescope at a spatial resolution of $\approx$ 100pc. We have identified
two-components in the line emitting gas. A narrower component (FWHM $\approx$
60-100km s$^{-1}$), which appears to be gas in the galaxy disk, and which shows
a distorted rotation pattern, is observed over the whole field of view. A
broader component (FWHM $\approx$150-250 km s$^{-1}$) is present in the inner
$\approx$ 2arcsec (200pc) and shows blueshifts and redshifts in the near and
far sides of the galaxy, respectively, consistent with a bipolar outflow.
Assuming this to be the case, we estimate that the mass outflow rate in ionized
gas ($\dot{M}_{out}$) is between 1.9 $\times 10^{-3}$M$_{\odot}$ yr$^{-1}$ and
6.9 $\times 10^{-3}$M$_{\odot}$ yr$^{-1}$. The subtraction of a rotation model
from the narrower component velocity field reveals a pattern of excess
blueshifts of $\approx$ 50km s$^{-1}$ in the far side of the galaxy and similar
excess redshifts in the near side, which are cospatial with a previously known
nuclear bar. We interpret these residuals as due to gas following non-circular
orbits in the barred potential. Under the assumption that these motions may
lead to gas inflows, we estimate an upper limit for the mass inflow rate in
ionized gas of $\phi$ $\approx$ 1.3 $\times 10^{-2}$M$_{\odot}$ yr$^{-1}$.
