Now that detection of gravitational-wave signals from the coalescence of extra-galactic
compact binary star mergers has become nearly routine, it is intriguing to consider other …

Scalarization is a mechanism that endows strongly self-gravitating bodies, such as neutron
stars and black holes, with a scalar-field configuration. It resembles a phase transition in that …

PSR J0740+ 6620 has a gravitational mass of 2.08±0.07 M⊙, which is the highest reliably
determined mass of any neutron star. As a result, a measurement of its radius will provide …

We report on Bayesian estimation of the radius, mass, and hot surface regions of the
massive millisecond pulsar PSR J0740+ 6620, conditional on pulse-profile modeling of …

We report on Bayesian parameter estimation of the mass and equatorial radius of the
millisecond pulsar PSR J0030+ 0451, conditional on pulse-profile modeling of Neutron Star …

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 brightest …

Neutron stars are not only of astrophysical interest, but are also of great interest to nuclear
physicists because their attributes can be used to determine the properties of the dense …

Observations of neutron-star mergers with distinct messengers, including gravitational
waves and electromagnetic signals, can be used to study the behavior of matter denser than …

X-ray pulse profile modeling of PSR J 0740+ 6620, the most massive known pulsar, with
data from the NICER and XMM-Newton observatories recently led to a measurement of its …

Observations of neutron stars, whether in binaries or in isolation, provide information about
the internal structure of the most extreme material objects in the Universe. In this work, we …
