AthenaK Simulations of Magnetized Binary Neutron Star Mergers
Jacob Fields, David Radice
We present new numerical-relativity simulations of a magnetized binary neutron star merger performed with AthenaK. The simulations employ a temperature- and composition-dependent t…
Impact of Neutrino Flavor Conversions on Neutron Star Merger Dynamics, Ejecta, Nucleosynthesis, and Multi-Messenger Signals
Yi Qiu, David Radice, Sherwood Richers +3
We present numerical relativity simulations of binary neutron star mergers incorporating neutrino flavor transformations triggered by fast flavor instability, quantum many-body eff…
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…
Magnetic Field Configurations in Binary Neutron Star Mergers II: Inspiral, Merger and Ejecta
William Cook, Eduardo M. Gutiérrez, Sebastiano Bernuzzi +6
We perform a series of simulations of magnetised Binary Neutron Star mergers, with varying magnetic field topologies in the initial data, as well as varying Equations of State, and…
Investigating the Impact of Higher-Order Phase Transitions in Binary Neutron-Star Mergers
P. Hammond, A. Clevinger, M. Albino +10
In this paper we investigate quark deconfinement in neutrons stars and their mergers, focusing on the effects of higher orders for the phase transition between hadronic and quark m…
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…
Magnetic Flux Emergence in Binary Neutron Star Remnants
Jacob Fields, David Radice, Peter Hammond
Using high-resolution AthenaK simulations of a twisted toroidal flux tube, we study the flux emergence of magnetic structures in the shear layer of a hot massive neutron star typic…
Magnetic Field Configurations in Binary Neutron Star Mergers I: Post-merger Remnant and Disk
Eduardo M. Gutiérrez, William Cook, David Radice +6
We present a suite of general relativistic magnetohydrodynamic (GRMHD) simulations of binary neutron star (BNS) mergers performed with the code GR-Athena++. We investigate how a di…
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…
Neutrino Flavor Transformation in Neutron Star Mergers
Yi Qiu, David Radice, Sherwood Richers +1
We present the first numerical relativity simulations including neutrino flavor transformations that could result from flavor instabilities, quantum many-body effects, or potential…
