Neutron stars provide a window into the properties of dense nuclear matter. Several recent
observational and theoretical developments provide powerful constraints on their structure …

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 …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

The recent discovery by Advanced LIGO and Advanced Virgo of a gravitational wave signal
from a binary neutron star inspiral has enabled tests of general relativity (GR) with this new …

Combining the GW observations of merging systems of binary neutron stars and quasi-
universal relations, we set constraints on the maximum mass that can be attained by …

Despite their long history and astrophysical importance, some of the key properties of
neutron stars are still uncertain. The extreme conditions encountered in their interiors …

We review the physics of hyperons and Δ-resonances in dense matter in compact stars. The
covariant density functional approach to the equation of state and composition of dense …

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 …

On 17 August 2017, the LIGO and Virgo observatories made the first direct detection of
gravitational waves from the coalescence of a neutron star binary system. The detection of …
