An Analysis of AGN-Driven Outflows in the Seyfert 1 Galaxy NGC 3227

We have characterized the ionized, neutral, and warm molecular gas kinematics in the Seyfert 1 galaxy NGC 3227 using observations from the Hubble Space Telescope Space Telescope Imaging Spectrograph, Apache Point Observatory's Kitt Peak Ohio State Multi-Object Spectrograph, Gemini-North's Near-Infrared Integral Field Spectrometer, and the Atacama Large Millimeter Array. We fit multiple Gaussians to several spatially-resolved emission lines observed with long-slit and integral-field spectroscopy and isolate the kinematics based on apparent rotational and outflowing motions. We use the kinematics to determine an orientation for the bicone along which the outflows travel, and find that the biconical structure has an inclination of 40 ^+5-₄ from our line of sight, and a half-opening angle with an inner and outer boundary of 47 ^+6-₂ and 68 ^+1-₁, respectively. We observe ionized outflows traveling 500 km s^-1 at distances up to 7'' (800 pc) from the SMBH, and disturbed ionized gas up to a distance of 15'' (1. 7 kpc). Our analysis reveals that the ionized outflows are launched from within 20 pc of the SMBH, at the same location as a bridge of cold gas across the nucleus detected in ALMA CO (2-1) observations. We measure a turnover radius where the gas starts decelerating at a distance of 26 6 pc from the AGN. Compared to a turnover radius in the range of 31- 63 pc from a radiative driving model, we confirm that radiative driving is the dominant acceleration mechanism for the narrow line region (NLR) outflows in NGC 3227.
