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 GarcÃa RodrÃguez de Guzmán, Enrique Moguel +19
The first edition of the QuantumX track, held within the XXIX Jornadas de IngenierÃa del Software y Bases de Datos (JISBD 2025), brought together leading Spanish research groups w…
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
Binary neutron star mergers are expected to generate intense magnetic fields that power relativistic and non-relativistic outflows and shape their multimessenger signatures. These…
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…
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…
