Effects of Fluid Instabilities on Accretion Disk Spectra
S. W. Davis, O. M. Blaes, N. J. Turner +1
Numerical calculations and linear theory of radiation magnetohydrodynamic flows indicate that the photon bubble and magnetorotational instability (MRI) may produce large density in…
X-ray Reflection from Inhomogeneous Accretion Disks: I. Toy Models and Photon Bubbles
D. R. Ballantyne, N. J. Turner, O. M. Blaes
Numerical simulations of the interiors of radiation dominated accretion disks show that significant density inhomogeneities can be generated in the gas. Here, we present the first…
Using Multiwavelength Observations to Estimate the Black Hole Masses and Accretion Rates in Seyfert Galaxies
James Chiang, Omer Blaes
We model the spectral energy distribution of the type 1 Seyfert galaxies, fitting data from simultaneous optical, UV, and X-ray monitoring observations. We assume a geometry consis…
Turbulent Comptonization in Black Hole Accretion Disks
Aristotle Socrates, Shane W. Davis, Omer Blaes
In the inner-most regions of radiation pressure supported accretion disks, the turbulent magnetic pressure may greatly exceed that of the gas. If this is the case, it is possible f…
Local Radiative Hydrodynamic and Magnetohydrodynamic Instabilities in Optically Thick Media
Omer Blaes, Aristotle Socrates
We examine the local conditions for radiative damping and driving of short wavelength, propagating hydrodynamic and magnetohydrodynamic (MHD) waves in static, optically thick, stra…
A First Close Look at the Balmer Edge Behavior of the Quasar Big Blue Bump
Makoto Kishimoto, Robert Antonucci, Omer Blaes
We have found for the first time a Balmer edge feature in the polarized flux spectrum of a quasar (Ton 202). The edge feature is seen as a discontinuity in the slope, rather than a…
