Semi-Analytic Solutions For Warped, Super-Eddington Accretion Disks with Outflows
Gabriel Wohlfarth, Matthew Middleton, Omer Blaes +1
The discovery of billion solar mass black holes at high redshift challenges any standard Eddington-limited growth model. Previous work has shown that an advective accretion disk ca…
Geometrically Thin Sub-Eddington AGN Accretion Disks show a suppressed Lyman Edge
Ish Kaul, Yan-Fei Jiang, Omer Blaes +1
The observed ultraviolet continua of active galactic nuclei (AGN) generally lack a strong intrinsic HI Lyman edge predicted by classical optically thick accretion disk atmosphere m…
A Parameter Survey of Neutron Star Accretion Column Simulations
Lizhong Zhang, Omer Blaes, Yan-Fei Jiang
We conduct a parameter survey of neutron star accretion column simulations by solving the relativistic radiation MHD equations with opacities that account for strong magnetic field…
Magnetosonic Waves as a Driver of Observed Temperature Fluctuation Patterns in AGN Accretion Disks
Ish Kaul, Omer Blaes, Yan-Fei Jiang +1
Recent observations have revealed slow, coherent temperature fluctuations in AGN disks that propagate both inward and outward at velocities of , a kind of variabi…
Radiation and Magnetic Pressure Support in Accretion Disks around Supermassive Black Holes and The Physical Origin of the Extreme Ultraviolet to Soft X-ray Spectrum
Yan-Fei Jiang, Omer Blaes, Ish Kaul +1
We present the results of four three-dimensional radiation magnetohydrodynamic simulations of accretion disks around a solar mass black hole, which produce the far ultraviol…
Non-Stationary Discs and Instabilities
Omer Blaes, Yan-Fei Jiang, Jean-Pierre Lasota +1
We review our current knowledge of thermal and viscous instabilities in accretion discs around compact objects. We begin with classical disc models based on analytic viscosity pres…
