Local Stability of Strongly Magnetized Black Hole Tori
Maciek Wielgus, P. Chris Fragile, Ziming Wang +1
We investigate the local stability of strongly magnetized relativistic tori orbiting Kerr black holes, for the case of a purely toroidal magnetic field topology. Our approach encom…
The X-ray Flux Distribution of Sagittarius A* as Seen by Chandra
J. Neilsen, S. Markoff, M. A. Nowak +11
We present a statistical analysis of the X-ray flux distribution of Sgr A* from the Chandra X-ray Observatory's 3 Ms Sgr A* X-ray Visionary Project (XVP) in 2012. Our analysis indi…
Numerical Simulations of Optically Thick Accretion onto a Black Hole - II. Rotating Flow
P. Chris Fragile, Ally Olejar, Peter Anninos
In this paper we report on recent upgrades to our general relativistic radiation magnetohydrodynamics code, Cosmos++, including the development of a new primitive inversion scheme…
No Evidence for Bardeen-Petterson Alignment in GRMHD Simulations and Semi-Analytic Models of Moderately Thin, Prograde, Tilted Accretion Disks
Viacheslav V. Zhuravlev, Pavel B. Ivanov, P. Chris Fragile +1
In this paper we introduce the first results that use data extracted directly from numerical simulations as inputs to the analytic twisted disk model of Zhuravlev & Ivanov. In both…
Conservative GRMHD Simulations of Moderately Thin, Tilted Accretion Disks
Danilo Morales Teixeira, P. Chris Fragile, Viacheslav V. Zhuravlev +1
This paper presents our latest numerical simulations of accretion disks that are misaligned with respect to the rotation axis of a Kerr black hole. In this work we use a new, fully…
Update on 3D Moving Mesh Simulations of Galactic Center Cloud G2
P. Chris Fragile, Peter Anninos, Stephen D. Murray
Using three-dimensional, moving-mesh simulations, we investigate the future evolution of the recently discovered gas cloud G2 traveling through the galactic center. From our simula…
