A strongly hyperbolic viscous relativistic hydrodynamics theory with first-order charge current
Federico Schianchi, Fernando Abalos
We extend the first order dissipative relativistic hydrodynamics model of Bemfica-Disconzi-Noronha- Kovtun (BDNK) in order to include the charge number current in full first order…
MHDuet : a high-order General Relativistic Radiation MHD code for CPU and GPU architectures
Carlos Palenzuela, Miguel Bezares, Steven Liebling +12
We present MHDuet, an open source evolution code for general relativistic magnetohydrodynamics with neutrino transport. The code solves the full set of Einstein equations coupled t…
General-relativistic radiation magnetohydrodynamics simulations of binary neutron star mergers: The influence of spin on the multi-messenger picture
Anna Neuweiler, Henrique Gieg, Henrik Rose +8
The rich phenomenology of binary neutron star mergers offers a unique opportunity to test general relativity, investigate matter at supranuclear densities, and learn more about the…
Employing deep-learning techniques for the conservative-to-primitive recovery in binary neutron star simulations
Ranjith Mudimadugula, Federico Schianchi, Anna Neuweiler +3
The detection of GW170817, together with its electromagnetic counterparts, has proven that binary neutron star mergers are of central importance to the field of nuclear astrophysic…
On the Role of Muons in Binary Neutron Star Mergers: First Simulations
Henrique Gieg, Federico Schianchi, Maximiliano Ujevic +1
In this work we present a set of binary neutron star (BNS) merger simulations including the net muon fraction as an additional degree-of-freedom in the equation of state (EoS) and…
General Relativistic Magneto-Hydrodynamic Simulations with BAM: Implementation and Code Comparison
Anna Neuweiler, Tim Dietrich, Bernd Brügmann +7
Binary neutron star mergers are among the most energetic events in our Universe, with magnetic fields significantly impacting their dynamics, particularly after the merger. While n…
