Bayesian Inference of Stellar r-Process Abundances
Jan Kuske, Almudena Arcones, Isak Svensson
The abundances of heavy elements observed in metal-poor, r-process-enhanced stars provide unique information about the astrophysical conditions in which the rapid neutron-capture p…
Astrophysics equation of state inference with Bayesian chiral effective field theory uncertainties
Melissa Mendes, Hannah Göttling, Anna Hensel +5
We investigate Bayesian chiral effective field theory (EFT) uncertainties, which assign a statistical interpretation to equation of state (EOS) distributions near nuclear satur…
Equation-of-state-informed pulse profile modeling
Mariska Hoogkamer, Nathan Rutherford, Daniela Huppenkothen +9
NICER has enabled mass-radius inferences for pulsars using pulse profile modeling (PPM), providing constraints on the equation of state (EOS) of cold, dense matter. To date, PPM an…
Bayesian approach for many-body uncertainties in nuclear structure: Many-body perturbation theory for finite nuclei
Isak Svensson, Alexander Tichai, Kai Hebeler +1
A comprehensive assessment of theoretical uncertainties defines an important frontier in nuclear structure research. Ideally, theory predictions include uncertainty estimates that…
A NICER view of the 1.4 solar-mass edge-on pulsar PSR J0614-3329
Lucien Mauviard, Sebastien Guillot, Tuomo Salmi +20
Four neutron star radius measurements have already been obtained by modeling the X-ray pulses of rotation-powered millisecond pulsars observed by the Neutron Star Interior Composit…
Inferring three-nucleon couplings from multi-messenger neutron-star observations
Rahul Somasundaram, Isak Svensson, Soumi De +5
Understanding the interactions between nucleons in dense matter is an important challenge in theoretical physics. Effective field theories have emerged as the dominant approach to…
