Dynamical Bar-Mode Instability in Differentially Rotating Magnetized Neutron Stars
Karen D. Camarda, Peter Anninos, P. Chris Fragile +1
This paper presents a numerical study over a wide parameter space of the likelihood of the dynamical bar-mode instability in differentially rotating magnetized neutron stars. The i…
Effective Inner Radius of Tilted Black Hole Accretion Disks
P. Chris Fragile
One of the primary means of determining the spin of an astrophysical black hole is by actually measuring the inner radius of a surrounding accretion disk and using that to infer th…
Excitation of Trapped Waves in Simulations of Tilted Black Hole Accretion Disks with Magnetorotational Turbulence
Ken B. Henisey, Omer M. Blaes, P. Chris Fragile +1
We analyze the time dependence of fluid variables in general relativistic, magnetohydrodynamic simulations of accretion flows onto a black hole with dimensionless spin parameter a/…
Millimeter Flares and VLBI Visibilities from Relativistic Simulations of Magnetized Accretion onto the Galactic Center Black Hole
Jason Dexter, Eric Agol, P. Chris Fragile
The recent VLBI observation of the Galactic center black hole candidate Sgr A* at 1.3mm shows source structure on event-horizon scales. This detection enables a direct comparison o…
Gamma-Ray Burst Pulse Correlations as Redshift Indicators
Jon Hakkila, P. Chris Fragile, Timothy W. Giblin
Correlations among pulse properties in the prompt emission of long GRBs can potentially be used as cosmological distance indicators to estimate redshifts of GRBs to which these pul…
Low frequency QPO spectra and Lense-Thirring precession
Adam Ingram, Chris Done, P Chris Fragile
We show that the low frequency QPO seen in the power density spectra of black hole binaries (and neutron stars) can be explained by Lense-Thirring precession. This has been propose…
