Modeling the [Fe II]λ1.644μm outflow and comparison with H${}_2$ and H${}^{+}$ kinematics in the inner 200 pc of NGC 1068

Abstract

We map the kinematics of the inner (200 pc) narrow-line region (NLR) of the Seyfert 2 galaxy NGC 1068 using the instrument NIFS and adaptative optics at the Gemini North Telescope. Channel maps and position-velocity diagrams are presented at a spatial resolution of $\sim$ 10 pc and spectral resolution $\sim$ 5300 in the emission lines [Fe II] λ 1.644 μm, H${}_2$ λ 2.122 μm and Brγ. The [Fe II] emission line provides a better coverage of the NLR outflow than the previously used [O III] λ 5007 emission line, extending beyond the area of the bi-polar cone observed in Brγ and [O III]. This is mainly due to the contribution of the redshifted channels to the NE of the nucleus, supporting its origin in a partial ionized zone with additional contribution from shocks of the outflowing gas with the galactic disc. We modeled the kinematics and geometry of the [Fe II] emitting gas finding good agreement with the data for outflow models with conical and lemniscate (or hourglass) geometry. We calculate a mass outflow rate $1.9_{-0.7}^{+1.9}$ M${}_{\odot }$yr${}^{-1}$ but a power for the outflow of only 0.08% L${}_{Bol}$. The molecular (H${}_2$) gas kinematics is completely distinct from that of [Fe II] and Brγ, showing radial expansion in an off-centered $\sim$ 100 pc radius ring in the galaxy plane. The expansion velocity decelerates from $\sim$ 200 km/s in the inner border of the ring to approximately zero at the outer border where our previous studies found a 10 Myr stellar population.
