Nuclear equation-of-state and multi-messenger astronomy: contribution of heavy-ion collisions

Arnaud Le Fèvre (GSI, Darmstadt, Germany)

In the past decade, new instruments in the field of multi-messenger astronomy like LIGO, VIRGO and NICER have provided great measurements. In the meanwhile, an increasing precision in the determination of the nuclear equation-of-state has been reached in the field of nuclear experiments. Altogether, they allowed breakthroughs in the knowledge of neutron star properties, and in bridging nuclear experimental constraints for symmetric matter and asymmetric nuclear matter to neutron stars. In particular, we demonstrate how constraints from heavy-ion collisions play a crucial role in neutron star studies. In the near future, improvements in transport models and nuclear theories, new accelerator facilities, new experiments, in conjunction with new neutron star measurements with enhanced precision should allow exploring the golden era of neutron star physics with heavy-ions collisions, by bridging further micro- and macroscopic collisions.
