We summarize our current knowledge of neutron-star masses and radii. Recent
instrumentation and computational advances have resulted in a rapid increase in the …

The quest for binary and dual supermassive black holes (SMBHs) at the dawn of the multi-
messenger era is compelling. Detecting dual active galactic nuclei (AGN)–active SMBHs at …

The noise in millisecond pulsar (MSP) timing data can include contributions from observing
instruments, the interstellar medium, the solar wind, solar system ephemeris errors, and the …

We searched for an isotropic stochastic gravitational wave background in the second data
release of the International Pulsar Timing Array, a global collaboration synthesizing decadal …

Laboratory experiments sensitive to the equation of state of neutron rich matter in the vicinity
of nuclear saturation density provide the first rung in a “density ladder” that connects …

A bstract In recent years, several pulsar timing array collaborations have reported first hints
for a stochastic gravitational wave background at nano-Hertz frequencies. Here we …

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 …

The Advanced LIGO [1] and Advanced Virgo [2] detectors have made numerous detections
of gravitational waves (GWs), to date consisting of short-duration (transient) GWs emitted …

Fewer than a dozen gamma-ray pulsars were known when the Fermi Gamma-ray Space
Telescope was launched on 2008 June 11, and the extent and diversity of the population …

We present high-precision timing data over time spans of up to 11 years for 45 millisecond
pulsars observed as part of the North American Nanohertz Observatory for Gravitational …
