GRHayL: a modern, infrastructure-agnostic, extensible library for GRMHD simulations
Samuel Cupp, Leonardo R. Werneck, Terrence Pierre Jacques +2
Interpreting multimessenger signals from neutron stars and black holes requires reliable general relativistic magnetohydrodynamics (GRMHD) simulations across rapidly evolving high-…
Multi-messengers from the radioactive decay of -process nuclei
Axel Gross, Samuel Cupp, Matthew R. Mumpower
The radioactive -decay of nuclei synthesized in the rapid neutron capture process (-process) releases a variety of particles, including electrons, -rays, neutrinos, and…
Let there be neutrons! Hadronic photoproduction from a large flux of high-energy photons
Matthew R. Mumpower, Tsung-Shung H. Lee, Nicole Lloyd-Ronning +4
We propose that neutrons may be generated in high-energy, high-flux photon environments via photo-induced reactions on pre-existing baryons. These photohadronic interactions are ex…
Gamma-Ray Spectra of -Process Nuclei
Axel Gross, Samuel Cupp, Matthew R Mumpower
The radioactive decay of unstable nuclei created in the rapid neutron capture process releases a large amount of -rays. When the ejecta are optically thick, these -rays may…
Kilonovae and Long-duration Gamma-ray Bursts
Marko RistiÄ, Brandon L. Barker, Samuel Cupp +5
Recent detections of kilonova-like emission following long-duration gamma-ray bursts GRB211211A and GRB230307A have been interpreted as originating from the merger of two neutron s…
General relativistic hydrodynamics code for dynamical spacetimes with curvilinear coordinates, tabulated equations of state, and neutrino physics
Terrence Pierre Jacques, Samuel Cupp, Leonardo R. Werneck +3
Many astrophysical systems of interest to numerical relativity-such as rapidly rotating stars, black hole accretion disks, and core-collapse supernovae-exhibit near-symmetries. The…
