New Tests of Millilensing in the Blazar PKS 1413+135
A. L. Peirson, I. Liodakis, A. C. S. Readhead +26
Symmetric Achromatic Variability (SAV) is a rare form of radio variability in blazars that has been attributed to gravitational millilensing by a ~ mass cond…
Magnetized ICF Implosions: Scaling of Temperature and Yield Enhancement
C. A. Walsh, S. O'Neill, J. P. Chittenden +11
This paper investigates the impact of an applied magnetic field on the yield and hot-spot temperature of inertial confinement fusion implosions. A scaling of temperature amplificat…
The Unanticipated Phenomenology of the Blazar PKS~2131021: A Unique Super-Massive Black Hole Binary Candidate
S. O'Neill, S. Kiehlmann, A. C. S. Readhead +24
Most large galaxies host supermassive black holes in their nuclei and are subject to mergers, which can produce a supermassive black hole binary (SMBHB), and hence periodic signatu…
Quantifying energetics and dissipation in magnetohydrodynamic turbulence
Greg Salvesen, Kris Beckwith, Jacob B. Simon +2
We perform a suite of two- and three-dimensional magnetohydrodynamic (MHD) simulations with the Athena code of the non-driven Kelvin-Helmholtz instability in the subsonic, weak mag…
Local Simulations of Instabilities in Relativistic Jets I: Morphology and Energetics of the Current-Driven Instability
Sean M. O'Neill, Kris Beckwith, Mitchell C. Begelman
We present the results of a numerical investigation of current-driven instability in magnetized jets. Utilizing the well-tested, relativistic magnetohydrodynamic code Athena, we co…
Synthetic Observations of Simulated AGN Jets: X-ray Cavities
P. J. Mendygral, S. M. O'Neill, T. W. Jones
Observations of X-ray cavities formed by powerful jets from AGN in galaxy cluster cores are widely used to estimate the energy output of the AGN. Using methods commonly applied to…
On the Time Variability of Geometrically-Thin Black Hole Accretion Disks II: Viscosity-Induced Global Oscillation Modes in Simulated Disks
Sean M. O'Neill, Christopher S. Reynolds, M. Coleman Miller
We examine the evolution and influence of viscosity-induced diskoseismic modes in simulated black hole accretion disks. Understanding the origin and behavior of such oscillations w…
Galactic Magnetic Field Structure and Ultra High Energy Cosmic Ray Propagation
Sean O'Neill, Angela V. Olinto, Pasquale Blasi
We consider the effects of the Galactic magnetic field on the propagation of ultra high energy cosmic rays (UHECRs). By employing two methods of trajectory simulation, we investiga…
