Abstract: I discuss recent kinematic studies of the Narrow-Line Region (NLR) of nearby Active Galactic Nuclei (AGN) from observations obtained with near-infrared and optical Integral Field Spectrographs at the Gemini Telescopes. The ionized gas kinematics usually shows a combination of rotational motion and outflow. The flux distribution and outflow kinematics correlate with structures seen in radio maps, but in some cases the orientation of the two — optical and radio outflows — differ by up to a few tens of degrees. Outflow velocities range from a few to several hundreds of km/s, and the mass outflow rates from 0.5 to a few solar masses per year. These rates are 1 to 3 orders of magnitude larger than the mass accretion rate to the AGN, and its origin is thus entrainment of host galaxy gas by the AGN outflow. From the measured velocities and mass outflow rates, we estimate the kinetic power of the outflow; the result is usually smaller than 1 percent of the bolometric luminosity of the AGN.
