Fe Kα Lines of Seyfert I Galaxies: Thin-Torus Model
Published online by Cambridge University Press: 26 May 2016
Abstract
In order to elucidate the physics of the Fe Kα line emissions from Seyfert (-like) AGNs, we propose a thin-torus model in Kerr metric and fit it to three galaxies (i.e., NGC 3516, 3C 273, and NGC 5548). It is found that only spinning-BH galaxies radiate observable line flux from a region within tens of gravitational radii of a central BH. Besides, the observer's inclination angle is around 30°.
