The narrow-line region (NLR) in AGN plays a crucial role in understanding AGN structure and evolution, as well as the interaction between the nuclear engine and the ISM of host galaxies in the form of outflows. Here, we present results from the Chandra SOARS (Survey Outflows in AGN with Resolved Spectroscopy) program, a 1.4 Ms Chandra GO, GTO, and archival study to perform spatially resolved HETG spectroscopy of the kpc-scale NLRs in some of our nearest AGN, including the Circinus Galaxy, NGC 1068, and Mrk 3.
We use the sensitive line diagnostics offered by HETG to (1) measure the mass and energy imparted by the AGN outflow into its kpc-scale environment; and (2) create a full kinematic map of the galaxy, thereby directly constraining the extent of the outflow. Our results have key implications for the role of galactic-scale outflows in AGN as moderators of galaxy evolution, and may suggest that outflows have radically different properties in early- and late-type AGN.
