We apply an analytic Markov Chain Monte Carlo model to a sample of 18
AGN-driven biconical outflows that we identified from a sample of active
galaxies with double-peaked narrow emission lines at z < 0.1 in the Sloan
Digital Sky Survey. We find that 8/18 are best described as asymmetric bicones,
8/18 are nested bicones, and 2/18 are symmetric bicones. From the geometry and
kinematics of the models, we 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. We find that 16/18 (89%) outflows are
energetic enough 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.Comment: 32 pages, 11 figures, accepted for publication in MNRAS; See Figure 7
