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…
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…
A NICER View of the Nearest and Brightest Millisecond Pulsar: PSR J0437$\unicode{x2013}$4715
Devarshi Choudhury, Tuomo Salmi, Serena Vinciguerra +17
We report Bayesian inference of the mass, radius and hot X-ray emitting region properties - using data from the Neutron Star Interior Composition ExploreR (NICER) - for the brighte…
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…
Constraining bosonic asymmetric dark matter with neutron star mass-radius measurements
Nathan Rutherford, Geert Raaijmakers, Chanda Prescod-Weinstein +1
Neutron stars can accumulate asymmetric dark matter (ADM) in their interiors, which affects the neutron star's measurable properties and makes compact objects prime targets to sear…
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…
