Turbulent Dynamo Action in Binary Neutron Star Mergers

Eduardo M. Gutiérrez, David Radice, Jacob Fields +1

Binary neutron star mergers are expected to generate intense magnetic fields that power relativistic and non-relativistic outflows and shape their multimessenger signatures. These…

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…

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…

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…

Not-Quite-Transcendental Functions For Logarithmic Interpolation of Tabulated Data

Peter C. Hammond, Jacob M. Fields, Jonah M. Miller +1

From tabulated nuclear and degenerate equations of state to photon and neutrino opacities, to nuclear reaction rates: tabulated data is ubiquitous in computational astrophysics. Th…

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…
