Description
Considerable efforts to investigate the equation of state (EOS) of dense matter by observing gravitational waves (GWs) from neutron star mergers, mainly by constraining the neutron star radius, have been made in recent years. However, a wide array of phenomena cannot be studied just by investigating the static properties of nuclear matter. With next-generation GW detectors anticipated for the next decade, there will soon be exciting, new opportunities to probe effects beyond the EOS in nuclear matter, in particular, with GW signals emitted by massive neutron star remnants that form after a merger.To learn as much as possible from the forthcoming observations of post-merger GW and multi-messenger counterpart signals, significant improvements in our understanding and capabilities of how nuclear matter behaves in these extreme environments are necessary. Beyond the equation-of-state physics like flavor equilibration, neutrino physics, exotic degrees of freedom, (color-) superfluidity and superconductivity, and beyond-the-standard-model particles might leave direct measurable imprints on observed signals. Furthermore, these effects, if ignored in the investigation of the equation of state, will lead to systematic errors that will make a correct and precise determination of the EOS impossible.
This workshop will bring together different areas of nuclear physics, astrophysics, and gravitational theory to discuss the necessary steps and advances required for us to fully leverage the opportunities posed by multi-messenger gravitational astronomy in the coming years and beyond.
