NICER neutron stars with dark energy and dark matter: effects on the inferred equation of state
Nathan Rutherford, Chanda Prescod-Weinstein, Anna Watts
[Abridged] In this work, we compare neutron stars where dark energy or dark matter are present in the core, contrasting them against purely baryonic stars with the same central ene…
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…
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…
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…
Probing fermionic asymmetric dark matter cores using global neutron star properties
Nathan Rutherford, Chanda Prescod-Weinstein, Anna Watts
It is possible for asymmetric dark matter (ADM) to accumulate in neutron star interiors and affect their global properties. Considering the effects of this accumulation, neutron st…
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…
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…
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…
