Cosmos++: Relativistic Magnetohydrodynamics on Unstructured Grids with Local Adaptive Refinement
Peter Anninos, P. Chris Fragile, Jay D. Salmonson
A new code and methodology are introduced for solving the general relativistic magnetohydrodynamic (GRMHD) equations in fixed background spacetimes using time-explicit, finite-volu…

Iron-Line Emission as a Probe of Bardeen-Petterson Accretion Disks
P. Chris Fragile, Warner A. Miller, Eric Vandernoot
In this work we show that Bardeen-Petterson accretion disks can exhibit unique, detectable features in relativistically broadened emission line profiles. Some of the unique charact…

Quasi-Periodic Oscillations in Relativistic Tori
P. Chris Fragile
Motivated by recent interesting work on p-mode oscillations in axisymmetric hydrodynamic black-hole tori by Rezzolla, Zanotti, and collaborators, I explore the robustness of these…
