  • Three-nucleon coupling strength in effective field theories of quantum chromodynamics (QCD) are typically constrained using few-body data. Here, authors leverage efficient computational techniques to determine such couplings from multi-messenger neutron star observations.

  • The physics of dense matter extracted from neutron star collision data is demonstrated to be consistent with information obtained from heavy-ion collisions, and analyses incorporating both data sources as well as information from nuclear theory provide new constraints for neutron star matter.

  • The Nuclear-physics and Multi-Messenger Astrophysics framework, NMMA, combines multiple information from neutron stars and neutron star mergers. Here, the authors show an update of the NMMA framework to constrain neutron star equation of state by simultaneously analyzing multi-messenger observations.

  • The combination of electromagnetic and gravitational-wave observations of binary neutron-star merger GW170817 with systematic sets of neutron-star equations of state has produced a tightly constrained radius of 11 km for a 1.4 M⊙ neutron star. This constraint suggests that a neutron star–black hole merger is unlikely to produce an electromagnetic counterpart.
