Joint Mass-Radius and Magnetic-Geometry Inference of PSR J0740+6620
Chun Huang, Tuomo Salmi, Alexander Y. Chen
X-ray pulse-profile modeling can measure neutron-star radii, but its physical interpretation remains limited by the largely phenomenological description of the surface hotspots. He…

Combining the Mass--Radius Posteriors of J0030+0451 Allowing for Unknown Model Systematics
Ryan O'Connor, Chun Huang, Alexander Y. Chen
The NASA Neutron star Interior Composition Explorer (\emph{NICER}) mission measures the X-ray pulse profiles of select millisecond pulsars and uses sophisticated pulse profile mode…
