Active Galactic Nuclei: The TeV Challenge
R. Blandford, W. East, K. Nalewajko +2
Jets associated with Active Galactic Nuclei (AGN) have been observed for almost a century, initially at optical and radio wavelengths. They are now widely accepted as "exhausts" pr…
Beginning inflation in an inhomogeneous universe
William E. East, Matthew Kleban, Andrei Linde +1
Using numerical solutions of the full Einstein field equations coupled to a scalar inflaton field in 3+1 dimensions, we study the conditions under which a universe that is initiall…
Relativistic Simulations of Eccentric Binary Neutron Star Mergers: One-arm Spiral Instability and Effects of Neutron Star Spin
William E. East, Vasileios Paschalidis, Frans Pretorius +1
We perform general-relativistic hydrodynamical simulations of dynamical capture binary neutron star mergers, emphasizing the role played by the neutron star spin. Dynamical capture…
One-arm Spiral Instability in Hypermassive Neutron Stars Formed by Dynamical-Capture Binary Neutron Star Mergers
Vasileios Paschalidis, William E. East, Frans Pretorius +1
Using general-relativistic hydrodynamical simulations, we show that merging binary neutron stars can form hypermassive neutrons stars that undergo the one-arm spiral instability. W…
Freely decaying turbulence in force-free electrodynamics
Jonathan Zrake, William E. East
Freely decaying relativistic force-free turbulence is studied for the first time. We initiate the magnetic field at a short wavelength and simulate its relaxation toward equilibriu…
Eccentric mergers of black holes with spinning neutron stars
William E. East, Vasileios Paschalidis, Frans Pretorius
We study dynamical capture binary black hole-neutron star (BH-NS) mergers focusing on the effects of the neutron star spin. These events may arise in dense stellar regions, such as…
