Lyman Edge Features from Accretion Disks Around Maximally Rotating Supermassive Black Hole

Autor: Sincell, Mark W.

We calculate the amplitude of the Lyman discontinuity for an accretion disk around a maximally rotating black hole. The locally emitted disk spectrum is computed with a previously developed numerical model (Sincell and Krolik 1998) and then a new gen

The Vertical Structure and Ultraviolet Spectrum of Accretion Disks Heated by Internal Dissipation in Active Galactic Nuclei

Autor: Sincell, Mark W., Krolik, Julian H.

We present an improved calculation of the vertical structure and ultraviolet spectrum of a dissipative accretion disk in an AGN. We calculate model spectra in which the viscous stress is proportional to the total pressure, the gas pressure only and t

Multi-Wavelength Variability of the Synchrotron Self-Compton Model for Blazar Emission

Autor: Sincell, Mark W.

Motivated by recent reports of strongly correlated radio and X-ray variability in 3C279 (Grandi, etal 1995), we have computed the relative amplitudes of variations in the synchrotron flux at $\nu$ and the self-Compton X-ray flux at 1 keV ($R(\nu)$) f

Report

The Vertical Structure and Ultraviolet Spectrum of X-Ray Irradiated Accretion Disks in Active Galactic Nuclei

Autor: Sincell, Mark W., Krolik, Julian H.

Motivated by recent work indicating that the UV continuum in AGN may be produced by reradiation of energy absorbed from X-rays irradiating an accretion disk, we present a calculation of the vertical structures and ultraviolet spectra of X-ray irradia
