The Polish doughnuts revisited I. The angular momentum distribution and equipressure surfaces
L. Qian, M. A. Abramowicz, P. C. Fragile +3
We construct a new family of analytic models of black hole accretion disks in dynamical equilibria. Our construction is based on assuming distributions of angular momentum and entr…
General Relativistic Magnetohydrodynamic Simulations of the Hard State as a Magnetically-Dominated Accretion Flow
P. Chris Fragile, David L. Meier
(Abridged) We present one of the first physically-motivated two-dimensional general relativistic magnetohydrodynamic (GRMHD) numerical simulations of a radiatively-cooled black-hol…
Epicyclic Motions and Standing Shocks in Numerically Simulated Tilted Black-Hole Accretion Disks
P. Chris Fragile, Omer M. Blaes
This work presents a detailed analysis of the overall flow structure and unique features of the inner region of the tilted disk simulations described in Fragile et al. (2007). The…
Correlations Between Lag, Luminosity, and Duration in Gamma-ray Burst Pulses
Jon Hakkila, Timothy W. Giblin, Jay P. Norris +2
We derive a new peak lag vs. peak luminosity relation in gamma-ray burst (GRB) pulses. We demonstrate conclusively that GRB spectral lags are pulse rather than burst properties and…
