Finite-Solid-Angle Boltzmann Radiation Transport on Dynamical Spacetimes in AthenaK
Hengrui Zhu, Alexander J. Dittmann, Lizhong Zhang +3
We extend the finite-solid-angle general relativistic radiation transport method of C. J. White et al. (2023) to time-dependent spacetimes represented in ADM form. This Valencia-ty…
QuantumX: an experience for the consolidation of Quantum Computing and Quantum Software Engineering as an emerging discipline
Juan M. Murillo, Ignacio García Rodríguez de Guzmán, Enrique Moguel +19
The first edition of the QuantumX track, held within the XXIX Jornadas de Ingeniería del Software y Bases de Datos (JISBD 2025), brought together leading Spanish research groups wo…
GR-Athena++: Binary Neutron Star Merger Simulations with Neutrino Transport
Boris Daszuta, Sebastiano Bernuzzi, Maximilian Jacobi +4
We present general-relativistic radiation magnetohydrodynamics simulations of binary neutron star mergers performed with GR-Athena++. Neutrino transport is treated using a moment-b…
Turbulent Dynamo Action in Binary Neutron Star Mergers
Eduardo M. Gutiérrez, David Radice, Jacob Fields +1
We perform general-relativistic magnetohydrodynamics zoom-in simulations of the merger of two neutron stars starting with pulsar-like realistic initial magnetic field. We employ un…
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…
