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…
Remnant properties of binary neutron star mergers undergoing prompt collapse
Arnab Dhani, Alessandro Camilletti, David Radice +4
We study the properties of remnants formed in prompt-collapse binary neutron star mergers. We consider non-spinning binaries over a range of total masses and mass ratios across a s…
Direct Measurement of the Accretion Disk Formed in Prompt Collapse Mergers with Future Gravitational-Wave Observatories
Arnab Dhani, Alessandro Camilletti, Alessio Ludovico De Santis +6
The production site of heavy r-process elements, such as Gold and Uranium, is uncertain. Neutron star mergers are the only astrophysical phenomenon in which we have witnessed their…
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…
