TITAN mass measurements of neutron-rich Cs, Ba and r-process lanthanide abundances
T. -H. Yeh, J. D. Cardona, Y. Wang +26
We present measurements for the masses of five neutron-rich isotopes, Cs and Ba, probed for the first time by TITAN at TRIUMF with time-of-flight measureme…
Beta-Particle Transport and Thermalization in Kilonova Ejecta with Detailed Atomic Microphysics
Zachary L. Andalman, Christopher L. Fryer, Christopher J. Fontes +2
When two neutron stars collide, they eject material containing heavy nuclei formed by the rapid neutron capture process (-process). As these nuclei decay, they power a bright op…
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…
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…
Joint Electromagnetic and Gravitational Wave Inference of Binary Neutron Star Merger GW170817 Using Forward-Modeling Ejecta Predictions
Marko RistiÄ, Richard O'Shaughnessy, Kate Wagner +5
We reassess the capacity for multimessenger inference of AT2017gfo/GW170817 using both kilonova and gravitational wave emission within the context of a recent simulation-based surr…
