In recent years, machine learning has emerged as a powerful computational tool and novel
problem-solving perspective for physics, offering new avenues for studying strongly …

We review the present status of the experimental and theoretical developments in the field of
strangeness in nuclei and neutron stars. We start by discussing the K ̄ N interaction, that is …

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 update the capabilities of the software instrument Modules for Experiments in Stellar
Astrophysics (MESA) and enhance its ease of use and availability. Our new approach to …

The dense matter equation of state (EOS) determines neutron star (NS) structure but can be
calculated reliably only up to one to two times the nuclear saturation density, using accurate …

During 2014 and 2015, NASA's Neutron star Interior Composition Explorer (NICER) mission
proceeded success-fully through Phase C, Design and Development. An X-ray (0.2-12 keV) …

In this article, I introduce ideas and techniques to extract information about the equation of
state of matter at very high densities from gravitational waves emitted before, during and …

Quasi-periodic eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of
galaxies, repeating on timescales of hours to weeks,,,–. The mechanism behind these rare …

Neutron stars and quark stars are ideal laboratories to study fundamental physics at supra
nuclear densities and strong gravitational fields. Astrophysical observables, however …

We present the drastic transformation of the X-ray properties of the active galactic nucleus
(AGN) 1ES 1927+ 654, following a changing-look event. After the optical/ultraviolet outburst …
