Signs of Flows and Shocks in Variable Balmer Line Profiles of the Seyfert Galaxies NGC 3227 and NGC 7469

Abstract: There is a widely held opinion that the narrow components of the emission line profiles in the spectra of AGNs are produced by gas streams and flows. The spectral data obtained and collected for the Seyfert galaxies NGC 3227 and NGC 7469 showed that the profiles of the Balmer lines contain components that maintained their positions over 9-25 years. We suppose that the components can be caused by long-lived flows or jets in broad-line regions. Night-to-night variations in the emission line H b and H g profiles … Show more
