Abstract

Over the last few years, we have been looking for inflows and outflows in the inner tens to hundred of parsecs of nearby active galactic nuclei (AGN) using integral field spectroscopy (IFS) at the Gemini telescopes. In particular, the use of the instrument NIFS+ALTAIR has allowed adequate spatial resolution to map the kinematics and excitation of both the molecular (H_2) and ionized gas, which shows that: (i) the H_2 emitting gas is usually either settled in rotation in the galactic plane or inflowing towards the center, (ii) the [FeII] and Br_gamma emitting gas kinematics is usually dominated by jet or wind-like morphologies in outflow. But only the most recent data (3 objects) have adequate information - spectroscopy covering at least the J and K bands - to homogeneously quantify these processes, including the mapping of the stellar population and kinematics. In order to build a consistent scenario for the feeding and feedback processes in AGN, relating them to the AGN power, we need to collect similar data for a larger sample, covering a range of AGN power. Towards this goal, we are now asking for J and K-band spectroscopy of one more AGN: the Seyfert 2 galaxy NGC5929.
