Extending the infrastructure of the BAM code towards resistive general-relativistic magnetohydrodynamics: tests and first applications
Matthew Beaudoin, Maximilano Ujevic, Ramon Jaeger +4
The paper extends the BAM numerical‑relativity code to include resistive general‑relativistic magnetohydrodynamics, validates it with benchmark tests, and applies it to isolated an…
A unified study of nuclear physics and dark matter constraints through gravitational-wave observations of binary neutron star mergers
Nina Kunert, Guilherme Grams, William Newton +5
Understanding the properties of strongly interacting matter at extreme densities is a central problem in fundamental physics, but neutron star mergers provide a natural laboratory…
Challenging a binary neutron star merger interpretation of GW230529
Ivan Markin, Anna Puecher, Mattia Bulla +1
GW230529_181500 represented the first gravitational-wave detection with one of the component objects' mass inferred to lie in the previously hypothesized mass gap between the heavi…
ESO Expanding Horizon White Paper: Revealing the properties of matter at supranuclear densities with gravitational waves
Tim Dietrich, Tanja Hinderer, Micaela Oertel +40
Understanding dense matter under extreme conditions is one of the most fundamental puzzles in modern physics. Complex interactions give rise to emergent, collective phenomena. Whil…
Numerical Relativity Simulations of Dark Matter Admixed Binary Neutron Stars
Edoardo Giangrandi, Hannes R. Rüter, Nina Kunert +7
Binary neutron star mergers provide insight into strong-field gravity and the properties of ultra-dense nuclear matter. These events offer the potential to search for signatures of…
Simulating Binary Neutron Star Mergers with Finite-temperature Equations of State: The influences of the slope of the symmetry energy and artificial heating
Henrique Gieg, Maximiliano Ujevic, Armen Sedrakian +1
We present a new set of numerical-relativity simulations of merging binary neutron stars, aiming to identify possible observable signatures of the slope of the symmetry energy $L_{…
