Accurate Evolution of Orbiting Binary Black Holes
Peter Diener, Frank Herrmann, Denis Pollney +5
We present a detailed analysis of binary black hole evolutions in the last orbit, and demonstrate consistent and convergent results for the trajectories of the individual bodies. T…
New, efficient, and accurate high order derivative and dissipation operators satisfying summation by parts, and applications in three-dimensional multi-block evolutions
Peter Diener, Ernst Nils Dorband, Erik Schnetter +1
We construct new, efficient, and accurate high-order finite differencing operators which satisfy summation by parts. Since these operators are not uniquely defined, we consider sev…
Non-symmetric trapped surfaces in the Schwarzschild and Vaidya spacetimes
Erik Schnetter, Badri Krishnan
Marginally trapped surfaces (MTSs) are commonly used in numerical relativity to locate black holes. For dynamical black holes, it is not known generally if this procedure is suffic…
Gravitational-Wave Emission from Rotating Gravitational Collapse in three Dimensions
L. Baiotti, I. Hawke, L. Rezzolla +1
We present the first calculation of gravitational wave emission produced in the gravitational collapse of uniformly rotating neutron stars to black holes in fully three-dimensional…
Computational Relativistic Astrophysics With Adaptive Mesh Refinement: Testbeds
Edwin Evans, Sai Iyer, Erik Schnetter +4
We have carried out numerical simulations of strongly gravitating systems based on the Einstein equations coupled to the relativistic hydrodynamic equations using adaptive mesh ref…
