Scientific paper

We present a study of the resolved narrow emission-line regions in the Seyfert galaxy Mrk 573, and their interaction with an inner dust/gas disk, based on Hubble Space Telescope (HST) WFPC2 and STIS observations. We determine that the bicone of ionizing radiation from the active galactic nucleus (AGN) intersects with the inner disk, illuminating a section of the disk including inner segments of spiral arms that appear to be expanding due to their interaction with the outflow. From the spectroscopic and imaging information, we determined the geometry of the biconical outflow, including its inclination, position angle, and opening angle via two modeling programs used to recreate the morphology of these regions imaged with HST.
