X-ray Polarization from Accreting Black Holes: Coronal Emission
Jeremy D. Schnittman, Julian H. Krolik
We present new calculations of X-ray polarization from accreting black holes (BHs), using a Monte-Carlo ray-tracing code in full general relativity. In our model, an optically thic…
Estimating the Prompt Electromagnetic Luminosity of a Black Hole Merger
Julian H. Krolik
Although recent work in numerical relativity has made tremendous strides in quantifying the gravitational wave luminosity of black hole mergers, very little is known about the elec…
A Vigorous Explorer Program
Martin Elvis, Matthew Beasley, Roger Brissenden +47
Explorers have made breakthroughs in many fields of astrophysics. The science from both these missions contributed to three Nobel Prizes - Giacconi (2002), Mather, and Smoot (2006)…
General Relativistic MHD Jets
J. H. Krolik, J. Hawley
Magnetic fields connecting the immediate environs of rotating black holes to large distances appear to be the most promising mechanism for launching relativistic jets, an idea firs…
What Is The Numerically Converged Amplitude of MHD Turbulence in Stratified Shearing Boxes?
Ji-Ming Shi, Julian H. Krolik, Shigenobu Hirose
We study the properties of the turbulence driven by the magnetorotational instability (MRI) in a stratified shearing box with outflow boundary conditions and an equation of state d…
Turbulent Stresses in Local Simulations of Radiation-Dominated Accretion Disks, and the Possibility of the LIghtman-Eardley Instability
Shigenobu Hirose, Omer Blaes, Julian H. Krolik
We present the results of a series of radiation-MHD simulations of a local patch of an accretion disk, with fixed vertical gravity profile but with different surface mass densities…
The Effects of Magnetic Fields and Inhomogeneities on Accretion Disk Spectra and Polarization
S. W. Davis, O. M. Blaes, S. Hirose +1
We present the results of one and three-dimensional radiative transfer calculations of polarized spectra emerging from snapshots of radiation magnetohydrodynamical simulations of t…
Host Galaxies of Luminous Type 2 Quasars at z ~ 0.5
Xin Liu, Nadia L. Zakamska, Jenny E. Greene +3
We present deep Gemini GMOS optical spectroscopy of nine luminous quasars at redshifts z ~ 0.5, drawn from the SDSS type 2 quasar sample. Our targets were selected to have high int…
GRMHD prediction of coronal variability in accreting black holes
Scott C. Noble, Julian H. Krolik
On the basis of data from an energy-conserving 3D general relativistic MHD simulation, we predict the statistical character of variability in the coronal luminosity from accreting…
X-ray Polarization from Black Holes in the Thermal State
Jeremy D. Schnittman, Julian H. Krolik
We present new calculations of X-ray polarization from black hole accretion disks in the thermally-dominated state, using a Monte-Carlo ray-tracing code in full general relativity.…
Transport of Large Scale Poloidal Flux in Black Hole Accretion
Kris Beckwith, John F. Hawley, Julian H. Krolik
We report on a global, three-dimensional GRMHD simulation of an accretion torus embedded in a large scale vertical magnetic field orbiting a Schwarzschild black hole. This simulati…
X-ray Polarization from Accreting Black Holes: II. The Thermal State
Jeremy D. Schnittman, Julian H. Krolik
We present new calculations of X-ray polarization from black hole (BH) accretion disks in the thermally-dominated state, using a Monte-Carlo ray-tracing code in full general relati…
