Mixing between Seyfert and H ii Region Excitation in Local Active Galaxies

Thomas, Adam; Kewley, Lisa; Dopita, Michael; Groves, Brent; Hopkins, Andrew M.; Sutherland, Ralph


We fit theoretical models to the emission-line spectra of 2766 Seyfert galaxies from the Sloan Digital Sky Survey (SDSS). The model line fluxes are derived by "mixing" photoionization model predictions of active galactic nucleus (AGN) narrow line region (NLR) emission and H ii region emission. The observed line fluxes in each spectrum were directly compared to the grid of mixed models using the Bayesian parameter estimation code NebulaBayes, thereby measuring the degree of mixing in each...[Show more]
