A NICER view of the millisecond pulsar PSR J21243358: evidence for a helium atmosphere
Denis González-Caniulef, Sebastien Guillot, Pierre Stammler +12
Pulse profile modeling has proven to be a powerful technique for determining the mass and radius of neutron stars. To date, this method has been applied to a handful of millisecond…
Pulse profile modelling of accreting millisecond pulsars with disc occultation and its impact on parameter inference
Ying-Han Mao, Bas Dorsman, Anna L. Watts +3
Pulse profile modelling is a relativistic ray-tracing technique used to infer neutron star mass, radius, and surface hotspot properties from X-ray pulsations. Pulse profile modelli…
Mass and radius measurements of the neutron star 47~Tuc X7 -- A new bias-free method
C. Kazantsev, S. Guillot, L. Mauviard +2
Neutron star (NS) radius measurements provide precious information to constrain the dense matter equation of state (EOS). Quiescent low-mass X-ray binaries (qLMXBs) have been used…
Pulse profile modelling of the 2024 outburst of the accreting millisecond pulsar SRGA J144459.2-604207
Bas Dorsman, Tuomo Salmi, Anna L. Watts +14
Pulse profile modelling via relativistic ray-tracing can constrain the system parameters of neutron stars, notably their mass and radius. Among these objects, accreting millisecond…
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…
Cross-Comparison of Sampling Algorithms for Pulse Profile Modeling of PSR J0740+6620
Mariska Hoogkamer, Yves Kini, Tuomo Salmi +2
In the last few years, NICER data has enabled mass and radius inferences for various pulsars, and thus shed light on the equation of state for dense nuclear matter. This is achieve…
