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…
Identifying observable MeV lines from the decays of weak and main -process isotopes in mergers
Maude Lariviere, Nicole Vassh, Yanwen Deng +2
We consider predictions for the MeV gamma-ray spectrum emitted by the decays of freshly synthesized isotopes from a neutron star merger at timescales of relevance for post-mer…
Constraining Nuclear Mass Models Using r-process Observables with Multi-objective Optimization
Mengke Li, Matthew Mumpower, Nicole Vassh +2
Predicting nuclear masses is a longstanding challenge. One path forward is machine learning (ML) which trains on experimental data, but can suffer large errors when extrapolating t…
Classifying metal-poor stars with machine learning using nucleosynthesis calculations
Nicole Vassh, Yilin Wang, Richard M. Woloshyn +4
We apply the capabilities of machine learning (ML) to discern patterns in order to classify metal-poor stars. To do so, we train an ML model on a bank of nucleosynthesis calculatio…
Multidisciplinary Science in the Multimessenger Era
Eric Burns, Christopher L. Fryer, Ivan Agullo +82
Astrophysical observations of the cosmos allow us to probe extreme physics and answer foundational questions on our universe. Modern astronomy is increasingly operating under a hol…
Motivations for Early High-Profile FRIB Experiments
B. Alex Brown, Alexandra Gade, S. Ragnar Stroberg +39
This white paper is the result of a collaboration by those that attended a workshop at the Facility for Rare Isotope Beams (FRIB), organized by the FRIB Theory Alliance (FRIB-TA),…
