Interior Magnetic Fields in Magnetars and Radio Pulsars
Raj Kishor Joshi, Brynmor Haskell, William Cook +1
Magnetic fields are fundamental for neutron star physics and play a central role in powering the extreme phenomenology of magnetars, including Soft Gamma Repeaters and Anomalous X-…
Subgrid Modelling for Relativistic Magnetohydrodynamics with Machine Learning
William Cook, Sebastiano Bernuzzi
Resolving the impact of magnetic field instabilities in triggering small scale turbulent flow and the associated rearrangement of the field is of critical importance in understandi…
Magnetic field dynamics in isolated neutron stars with an external dipole field
Aurora Capobianco, William Cook, Sebastiano Bernuzzi +2
Neutron stars can harbor extremely strong magnetic fields, yet the structure and stability of their magnetic field configuration remain poorly understood. Observations of pulsars i…
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…
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…
Turbulence in Magnetised Neutron Stars
William Cook, Raj Kishor Joshi, Sebastiano Bernuzzi +2
The magnetic field configuration in the interior of neutron stars and its stability are open problems and may be impacted by the influence of a turbulent cascade within the star. A…
Time-Variant Vector Field Visualization for Magnetic Fields of Neutron Star Simulations
Simon J. Lieb, William Cook, Jan Hombeck +2
We present a novel visualization application designed to explore the time-dependent development of magnetic fields of neutron stars. The strongest magnetic fields in the universe c…
Performance-Portable Binary Neutron Star Mergers with AthenaK
Jacob Fields, Hengrui Zhu, David Radice +4
We introduce an extension to the AthenaK code for general-relativistic magnetohydrodynamics (GRMHD) in dynamical spacetimes using a 3+1 conservative Eulerian formulation. Like the…
