Advances On Giant Nuclear Monopole Excitations And Applications To Multi-Messenger Astrophysics

11 Jul 2022, 09:00 → 15 Jul 2022, 17:00 Europe/Rome

Aula Renzo Leonardi (ECT*)

The giant monopole response of nuclei is intimately linked to the compressional properties of bulk nuclear matter. Recently much progress in the subject has been made both theoretically and experimentally. This also provides nuclear physics inputs of paramount importance for our modeling and understanding of core-collapse supernovae, neutron star properties, and merging of astrophysical compact objects.

This workshop will address three main topics of approximately equal importance: experimental, theoretical, and applications to multi-messenger astrophysics. The experimental advances center around new background-free measurements for stable nuclei and new techniques for unstable nuclei. The theoretical novelties include energy density functional calculations, ab initio approaches, and new methods for deducing the nuclear compression modulus. The astrophysics section will concentrate on the influence of nuclear equation of state parameters on astrophysical simulations and our understanding of recent observations of gravitational waves, electromagnetic signals, and neutrinos (that contribute to so-called “multi-messenger” astrophysics).
