While high luminosity quasar-driven outflows are commonly invoked as a means of driving feedback in galaxies, these are extreme cases, and the contribution of moderate luminosity AGN outflows to feedback is still unclear. I will present a sample of 18 moderate luminosity AGN outflows, which I have observed with optical longslit spectroscopy and modeled as biconical outflows using an analytic Markov Chain Monte Carlo method. From the geometry and kinematics of the models, I find that these moderate-luminosity AGN outflows are large and energetic. The biconical outflows axes are randomly oriented with respect to the photometric major axis of the galaxy, implying a randomly oriented and clumpier torus to collimate the outflow, but the torus also allows some radiation to escape equatorially. I find that 16/18 (89%) of the AGN outflows are energetic enough (L_KE/L_bol > 0.5%) to drive a two-staged feedback process in their host galaxies. All of these outflows geometrically intersect the photometric major axis of the galaxy, and 23% of outflow host galaxies are significantly redder or have significantly lower specific star formation rates when compared to a matched sample of active galaxies. Since moderate luminosity AGN are common in the local universe (10% of the AGN population, whereas high luminosity AGN are only 1% of the population), this suggests that moderate luminosity AGN may play an important role in driving feedback in the universe.
I would like to invite you to a 12 minute talk with a discussion following on AGN winds.
