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…
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…
Beta delayed neutron emission of Cd
M. Madurga, Z. Y. Xu, 1 R. Grzywacz +54
Using the time-of-flight technique, we measured the beta-delayed neutron emission of Cd. From our large-scale shell model (LSSM) calculation using the NLO interaction […
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…
Exploration for Astromers near Sn with the Canadian Penning Trap
A. A. Valverde, S. Cupp, A. Gross +26
Nuclear isomers can have significant impacts on astrophysical nucleosynthesis processes, with recent efforts demonstrating that the population of isomeric states with different hal…
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-…
