Abstract

Neutron stars, the remnants of supernova explosions, contain matter at densities far beyond what can be recreated in a lab. Understanding how this dense matter behaves is crucial for interpreting phenomena like neutron-star mergers. Despite advances in nuclear theory and experiments, many questions remain about the extreme conditions inside neutron stars. Fortunately, new observations are shedding light on these mysteries. In this talk, I will give an overview of the multi-messenger approach to studying neutron star matter, which combines data from sources such as nuclear theory, terrestrial nuclear experiments, and astrophysical observations of neutron stars. By integrating these datasets with Bayesian statistics, we obtain a state-of-the-art understanding of matter's behavior under the most extreme conditions in the Universe.
