Multiwavelength scaling relations for nuclei of Seyfert galaxies

摘要

We analyze an X-ray flux-limited, complete sample of 93 active galactic nuclei (AGNs) at, selected z < 0.1 from the ROSAT Bright Survey. Two-thirds of the sample are Seyfert 1 galaxies, and one-third are narrow-line Seyfert 1 galaxies. We have obtained optical images of all objects. By modeling the host galaxy and the AGN central component, we decompose the optical emission into nuclear bulge and disk components, respectively. We find that the nuclear optical luminosity, thought to be associated with the accretion disk surrounding the active black hole, correlates with the X-ray luminosity, the radio luminosity, and the black hole mass.
