Three-Dimensional General-Relativistic Hydrodynamic Simulations of Binary Neutron Star Coalescence and Stellar Collapse with Multipatch Grids
C. Reisswig, R. Haas, C. D. Ott +4
We present a new three-dimensional general-relativistic hydrodynamic evolution scheme coupled to dynamical spacetime evolutions which is capable of efficiently simulating stellar c…
Matching post-Newtonian and numerical relativity waveforms: systematic errors and a new phenomenological model for non-precessing black hole binaries
L. Santamaria, F. Ohme, P. Ajith +10
We present a new phenomenological gravitational waveform model for the inspiral and coalescence of non-precessing spinning black hole binaries. Our approach is based on a frequency…
Inspiral-merger-ringdown waveforms for black-hole binaries with non-precessing spins
P. Ajith, M. Hannam, S. Husa +9
We present the first analytical inspiral-merger-ringdown gravitational waveforms from binary black holes (BBHs) with non-precessing spins, that is based on a description of the lat…
Characteristic extraction in numerical relativity: binary black hole merger waveforms at null infinity
C. Reisswig, N. T. Bishop, D. Pollney +1
The accurate modeling of gravitational radiation is a key issue for gravitational wave astronomy. As simulation codes reach higher accuracy, systematic errors inherent in current n…
The NINJA-2 project: Detecting and characterizing gravitational waveforms modelled using numerical binary black hole simulations
The LIGO Scientific Collaboration, the Virgo Collaboration, 2 Collaboration +888
The Numerical INJection Analysis (NINJA) project is a collaborative effort between members of the numerical relativity and gravitational-wave astrophysics communities. The purpose…
Implementation of standard testbeds for numerical relativity
M. C. Babiuc, S. Husa, D. Alic +8
We discuss results that have been obtained from the implementation of the initial round of testbeds for numerical relativity which was proposed in the first paper of the Apples wit…
Phenomenological template family for black-hole coalescence waveforms
P. Ajith, S. Babak, Y. Chen +15
Recent progress in numerical relativity has enabled us to model the non-perturbative merger phase of the binary black-hole coalescence problem. Based on these results, we propose a…
Unambiguous determination of gravitational waveforms from binary black hole mergers
C. Reisswig, N. T. Bishop, D. Pollney +1
Gravitational radiation is properly defined only at future null infinity ($\scri$), but in practice it is estimated from data calculated at a finite radius. We have used characteri…
A template bank for gravitational waveforms from coalescing binary black holes: non-spinning binaries
P. Ajith, S. Babak, Y. Chen +15
Gravitational waveforms from the inspiral and ring-down stages of the binary black hole coalescences can be modelled accurately by approximation/perturbation techniques in general…
