The Stability of Radiatively Cooled Jets in Three Dimensions
Jianjun Xu, Philip Hardee, James Stone
The effect of optically thin radiative cooling on the Kelvin-Helmholtz instability of three dimensional jets is investigated via linear stability theory and nonlinear hydrodynamica…
Fundamental differences between SPH and grid methods
Oscar Agertz, Ben Moore, Joachim Stadel +17
We have carried out a hydrodynamical code comparison study of interacting multiphase fluids. The two commonly used techniques of grid and smoothed particle hydrodynamics (SPH) show…
Two-Dimensional Hydrodynamic Simulations of Convection in Radiation-Dominated Accretion Disks
Eric Agol, Julian Krolik, Neal Turner +1
The standard equilibrium for radiation-dominated accretion disks has long been known to be viscously, thermally, and convectively unstable, but the nonlinear development of these i…
A Higher Order Godunov Method for Radiation Hydrodynamics: Radiation Subsystem
Michael Sekora, James Stone
A higher order Godunov method for the radiation subsystem of radiation hydrodynamics is presented. A key ingredient of the method is the direct coupling of stiff source term effect…
Iron Opacity Bump Changes the Stability and Structure of Accretion Disks in Active Galactic Nuclei
Yan-Fei Jiang, Shane Davis, James Stone
Accretion disks around supermassive black holes have regions where the Rosseland mean opacity can be much larger than the electron scattering opacity primarily due to the large num…
The effects of irradiation on the cloud evolution in active galactic nuclei
Daniel Proga, Yan-Fei Jiang, James Stone +2
We report on the first phase of our study of cloud irradiation. We study irradiation by means of numerical, two-dimensional time-dependent radiation-hydrodynamic simulations of a c…
