The Narrow Emission Lines of Seyfert 1 Galaxies: Comparisons with a Large SDSS Sample
We analyzed a large sample of Sloan Digital Sky Survey spectra of Seyfert galaxies, subdividing type 1 Seyferts (Sy1s) based on their narrow to broad H α components. Comparing their narrow lines (NLs) to type 2 Seyferts (Sy2s) in line-ratio diagrams, most of the NLs of strong Sy1.0/Sy1.2s (with domi...
