Some First Steps Towards a Radiation GRMHD Code: Radiative Effects on Accretion Rate onto a Kerr Black Hole
Jean-Pierre De Villiers
The role of radiation in general relativistic magnetohydrodynamic (GRMHD) accretion simulations is discussed through axisymmetric simulations of the evolution of an initial torus s…
Stokes Theorem and the Equations of GRMHD
Jean-Pierre De Villiers
This paper provides an alternate derivation of the equations used in the GRMHD code of De Villiers and Hawley using Stokes Theorem. This derivation places the published form of the…
Accretion Disks in Large-scale Magnetic Fields
Jean-Pierre De Villiers
This paper presents a survey of a set of simulations of accretion disks orbiting a rapidly rotating Kerr black hole and embedded in a large-scale initial magnetic field. Each simul…
GRMHD Simulations of Disk/Jet Systems: Application to the Inner Engines of Collapsars
Jean-Pierre De Villiers, Jan Staff, Rachid Ouyed
We have carried out 2D and 3D general relativistic magnetohydrodynamic simulations of jets launched self-consistently from accretion disks orbiting Kerr black holes and applied the…
General Relativistic Magnetohydrodynamic Simulations of Black Hole Accretion Disks
J. F. Hawley, J. -P. De Villiers
Observations are providing increasingly detailed quantitative information about the accretion flows that power such high energy systems as X-ray binaries and active galactic nuclei…
Dynamics of Cosmic Strings in Schwarzschild Spacetime
Jean-Pierre De Villiers
Cosmic strings are topological defects thought to have formed early in the life of the universe. If such objects exist, a study of their interaction with black holes is of interest…
