Simulations of Spinning Binary Black Hole Mergers
Estuti Shukla, Alireza Rashti, Rossella Gamba +2
We present the second release of the waveform catalog, comprising four new quasi-circular, non-precessing, spinning binary black hole simulations. These simu…
Covariant and Gauge-invariant Metric-based Gravitational-waves Extraction in Numerical Relativity
Joan Fontbuté, Sebastiano Bernuzzi, Simone Albanesi +5
We revisit the problem of gravitational-wave extraction in numerical relativity with gauge-invariant metric perturbation theory of spherical spacetimes. Our extraction algorithm al…
Black-hole - neutron-star mergers: new numerical-relativity simulations and multipolar effective-one-body model with spin precession and eccentricity
Alejandra Gonzalez, Sebastiano Bernuzzi, Alireza Rashti +2
In this paper, we present 52 new numerical-relativity (NR) simulations of black-hole-neutron-star merger (BHNS) mergers and employ the data to inform TEOBResumS-Dalí: a multipolar…
AthenaK simulations of the binary black hole merger GW150914
David Radice, Rossella Gamba, Hengrui Zhu +1
We present new binary black hole simulations targeted to GW150914 using the GPU-accelerated code AthenaK. We compute the properties of the final remnant with the isolated horizon f…
Binary Black Hole Waveforms from High-Resolution GR-Athena++ Simulations
Alireza Rashti, Rossella Gamba, Koustav Chandra +4
The detection and subsequent inference of binary black hole signals rely heavily on the accuracy of the waveform model employed. In the highly non-linear, dynamic, and strong-field…
Performance-Portable Numerical Relativity with AthenaK
Hengrui Zhu, Jacob Fields, Francesco Zappa +6
We present the numerical relativity module within AthenaK, an open source performance-portable astrophysics code designed for exascale computing applications. This module employs t…
