Magnetized Neutron Star Mergers and Gravitational Wave Signals
Matthew Anderson, Eric W. Hirschmann, Luis Lehner +5
We investigate the influence of magnetic fields upon the dynamics of and resulting gravitational waves from a binary neutron star merger in full general relativity coupled to ideal…
Simulating binary neutron stars: dynamics and gravitational waves
Matthew Anderson, Eric W. Hirschmann, Luis Lehner +5
We model two mergers of orbiting binary neutron stars, the first forming a black hole and the second a differentially rotating neutron star. We extract gravitational waveforms in t…
Relativistic MHD with Adaptive Mesh Refinement
Matthew Anderson, Eric Hirschmann, Steven L. Liebling +1
This paper presents a new computer code to solve the general relativistic magnetohydrodynamics (GRMHD) equations using distributed parallel adaptive mesh refinement (AMR). The flui…
A Numerical Approach to Space-Time Finite Elements for the Wave Equation
Matthew Anderson, Jung-Han Kimn
We study a space-time finite element approach for the nonhomogeneous wave equation using a continuous time Galerkin method. We present fully implicit examples in 1+1, 2+1, and 3+1…
Tracking Black Holes in Numerical Relativity
Scott A. Caveny, Matthew Anderson, Richard A. Matzner
This work addresses and solves the problem of generically tracking black hole event horizons in computational simulation of black hole interactions. Solutions of the hyperbolic eik…
