A NICER view of PSR J16142230: a massive and compact millisecond pulsar
Lucien Mauviard, Sebastien Guillot, Lami Suleiman +17
Using pulse profile modeling, we obtain the mass-radius measurement of a millisecond pulsar (MSP) with data from the Neutron Star Interior Composition ExploreR, XMM-Newton and the…
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…
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…
A NICER View of PSR J0030+0451: Updated Constraints from Six Years of NICER Observations
Yves Kini, Lucien Mauviard, Tuomo Salmi +13
Pulse-profile modeling of rotation-powered millisecond pulsars targeted by NICER has enabled mass--radius constraints of several neutron star sources, with implications for the den…
Pulse profile modelling of the accretion-powered millisecond pulsar SAX J1808.4-3658 using NICER data from its 2019 and 2022 outbursts
Bas Dorsman, Tuomo Salmi, Anna L. Watts +5
Pulse profile modelling is a relativistic ray-tracing technique that has provided constraints on parameters, with a focus on mass and radius, of five rotation-powered millisecond p…
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…
Modelling polarized X-ray pulses from accreting millisecond pulsars with X-PSI, using different hot spot locations and shapes
Tuomo Salmi, Bas Dorsman, Anna L. Watts +7
We present an analysis of polarized X-ray pulses based on simulated data for accreting millisecond pulsars (AMPs). We used the open-source X-ray Pulse Simulation and Inference code…
Parameter constraints for accreting millisecond pulsars with synthetic NICER data
Bas Dorsman, Tuomo Salmi, Anna L. Watts +10
Pulse profile modelling (PPM) is a technique for inferring mass, radius and hotspot properties of millisecond pulsars. PPM is now regularly used for analysis of rotation-powered mi…
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…
Atmospheric Effects on Neutron Star Parameter Constraints with NICER
Tuomo Salmi, Serena Vinciguerra, Devarshi Choudhury +7
We present an analysis of the effects of uncertainties in the atmosphere models on the radius, mass, and other neutron star parameter constraints for the NICER observations of rota…
