A NICER View of PSR J12311411: A Complex Case
Tuomo Salmi, Julia S. Deneva, Paul S. Ray +16
Recent constraints on neutron star mass and radius have advanced our understanding of the equation of state (EOS) of cold dense matter. Some of them have been obtained by modeling…
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 More Precise Measurement of the Radius of PSR J0740+6620 Using Updated NICER Data
Alexander J. Dittmann, M. Coleman Miller, Frederick K. Lamb +9
PSR J0740+6620 is the neutron star with the highest precisely determined mass, inferred from radio observations to be . Measurements of its radius therefo…
The Radius of the High-mass Pulsar PSR J0740+6620 with 3.6 yr of NICER Data
Tuomo Salmi, Devarshi Choudhury, Yves Kini +14
We report an updated analysis of the radius, mass, and heated surface regions of the massive pulsar PSR J0740+6620 using Neutron Star Interior Composition Explorer (NICER) data fro…
Exploring Waveform Variations among Neutron Star Ray-tracing Codes for Complex Emission Geometries
Devarshi Choudhury, Anna L. Watts, Alexander J. Dittmann +8
Pulse Profile Modeling (PPM), the technique used to infer mass, radius and geometric parameters for rotation-powered millisecond pulsars using data from the Neutron Star Interior C…
Interpreting Mass and Radius Measurements of Neutron Stars with Dark Matter Halos
Shafayat Shawqi, Sharon M. Morsink
The high densities of neutron stars (NSs) could provide astrophysical locations for dark matter (DM) to accumulate. Depending on the DM model, these DM admixed NSs (DANSs) could ha…
