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…
Recoil velocities from equal-mass binary black-hole mergers: a systematic investigation of spin-orbit aligned configurations
Denis Pollney, Christian Reisswig, Luciano Rezzolla +8
Binary black-hole systems with spins aligned with the orbital angular momentum are of special interest, as studies indicate that this configuration is preferred in nature. If the s…
Excision without excision: the relativistic turducken
David Brown, Olivier Sarbach, Erik Schnetter +4
to turducken (turduckens, turduckening, turduckened, turduckened) [math.]: To stuff a black hole. We analyze and apply an alternative to black hole excision based on smoothing the…
How far away is far enough for extracting numerical waveforms, and how much do they depend on the extraction method?
Enrique Pazos, Ernst Nils Dorband, Alessandro Nagar +3
We present a method for extracting gravitational waves from numerical spacetimes which generalizes and refines one of the standard methods based on the Regge--Wheeler--Zerilli pert…
Gauge fixing for the simulation of black hole spacetimes
Erik Schnetter
I consider the initial-boundary-value-problem of nonlinear general relativistic vacuum spacetimes, which today cannot yet be evolved numerically in a satisfactory manner. Specifica…
A fast apparent horizon algorithm
Erik Schnetter
I present a fast algorithm to find apparent horizons. This algorithm uses an explicit representation of the horizon surface, allowing for arbitrary horizon resolutions and, in prin…
