We present a two-dimensional mapping of stellar population age components , emission-line fluxes , gas excitation and kinematics within the inner \sim 200 pc of the Seyfert 2 galaxy NGC 2110 .
We used the Gemini North Integral Field Spectrograph ( NIFS ) in the J and K bands at a spatial resolution of \sim 22 pc .
The unresolved nuclear continuum is originated in combined contributions of young stellar population ( SP ; age \leq 100 Myr ) , a featureless AGN continuum and hot dust emission .
The young-intermediate SP ( 100 < age \leq 700 Myr ) is distributed in a ring-shaped structure at \approx 140 pc from the nucleus , which is roughly coincident with the lowest values of the stellar velocity dispersion .
In the inner \approx 115 pc the old SP ( age > 2 Gyr ) is dominant .
The [ Fe ii ] \lambda 1.2570 \mu m emission-line flux distribution is correlated with the radio emission and its kinematics comprise two components , one from gas rotating in the galaxy plane and another from gas in outflow within a bicone oriented along north–south .
These outflows seem to originate in the interaction of the radio jet with the ambient gas producing shocks that are the main excitation mechanism of the [ Fe ii ] emission .
We estimate : ( 1 ) an ionized gas mass outflow rate of \sim 0.5 M _ { \odot } yr ^ { -1 } at \sim 70 pc from the nucleus ; and ( 2 ) a kinetic power for the outflow of only 0.05 % of the AGN bolometric luminosity implying weak feedback effect on the galaxy .
