Multiwavelength Analysis of the Outflows and Feedback Processes in the Seyfert 1 Galaxy NGC 3227
Description
NGC 3227 is a nearby star-forming Seyfert 1 galaxy that is tidally interacting with its neighbor NGC 3226. Our ongoing work concentrates on the connection and interplay between active galactic nuclei (AGN) and star formation-driven feeding and feedback in this galaxy. We present a detailed study of the kinematics and physical conditions of the ionized and molecular gas in NGC 3227 using multiwavelength observations in the radio, optical, and near-IR regimes. Using the Bayesian Evidence Analysis Tool (BEAT), we fit Gaussian profiles to the spatially resolved optical and near-IR emission lines observed in our long-slit and integral-field unit spectra. We use these two-dimensional kinematics to determine a best model for the orientation of the biconical structure along which the outflowing gas travels. We also use our fits to separate the rotational and outflow components of the narrow-line region gas so that we can determine the extent of outflowing gas within the galaxy and better characterize the gas motions at both nuclear and galactic scales. Our ultimate goal is to determine the mass outflow rates and evacuation time scales of the ionized and molecular gas in this nearby AGN.
