Bayesian analysis of the Coulomb breakup of C19

Quentin Bozet, Pierre Capel, Isak Svensson

Coulomb breakup is a common experimental technique to study the structure of halo nuclei. Coupling a halo effective field theory (Halo-EFT) description of these nuclei to accurate…

Equation of state and neutron star properties with new mass-radius constraints from PSR~J1614--2230, PSR~J2124--3358, and 47~Tuc~X7

Melissa Mendes, Isak Svensson, Hannah Gottling +9

We study the impact of new mass-radius information from PSR J1614-2230, PSR J2124-3358, and 47 Tuc X7 in a combined equation of state inference based on chiral effective field theo…

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 satura…

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…

Dense Matter in Neutron Stars with eXTP

Ang Li, Anna L. Watts, Guobao Zhang +82

In this White Paper, we present the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission to constrain the equation of state of dense matter in neutron stars, explo…

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…

Constraining the dense matter equation of state with new NICER mass-radius measurements and new chiral effective field theory inputs

Nathan Rutherford, Melissa Mendes, Isak Svensson +12

Pulse profile modeling of X-ray data from NICER is now enabling precision inference of neutron star mass and radius. Combined with nuclear physics constraints from chiral effective…
