2MASX J00423991+3017515: An offset active galactic nucleus in an interacting system
J. Drew Hogg, Laura Blecha, Christopher S. Reynolds +2
We present a spectroscopic and imaging study of an abnormal active galactic nucleus (AGN), 2MASX J00423991+3017515. This AGN is newly identified in the hard X-rays by the Swift BAT…
The influence of accretion disk thickness on the large-scale magnetic dynamo
J. Drew Hogg, Christopher Reynolds
The evolution of the magnetic field from the large-scale dynamo is considered a central feature of the accretion disk around a black hole. The resulting low-frequency oscillations…
The Dynamics of Truncated Black Hole Accretion Disks II: Magnetohydrodynamic Case
J. Drew Hogg, Christopher S. Reynolds
We study a truncated accretion disk using a well-resolved, semi-global magnetohydrodynamic simulation that is evolved for many dynamical times (6096 inner disk orbits). The spectra…
The Dynamics of Truncated Black Hole Accretion Disks I: Viscous, Hydrodynamic Case
J. Drew Hogg, Christopher S. Reynolds
Truncated accretion disks are commonly invoked to explain the spectro-temporal variability from accreting black holes in both small systems, i.e. state transitions in galactic blac…
Testing the Propagating Fluctuations Model with a Long, Global Accretion Disk Simulation
J. Drew Hogg, Christopher Reynolds
The broad-band variability of many accreting systems displays characteristic structure; log-normal flux distributions, RMS-flux relations, and long inter-band lags. These character…
Pre-Equilibrium Radial Flow from Central Shock-Wave Collisions in AdS5
Paul Romatschke, J. Drew Hogg
Using gauge/gravity duality, central ultrarelativistic nucleus-nucleus collisions are modelled as collisions of shock waves in five-dimensional asymptotic AdS space. For early time…
The Swift BAT Survey Detects Two Optical Broad Line, X-ray Heavily Obscured Active Galaxies: NVSS 193013+341047 and IRAS 05218-1212
J. Drew Hogg, Lisa M. Winter, Richard Mushotzky +2
The Swift Burst Alert Telescope (BAT) is discovering interesting new objects while monitoring the sky in the 14-195 keV band. Here we present the X-ray properties and spectral ener…
