Physics - Nuclear Physics Seminar

Neutrinos play an important role in determining the evolution of massive stars. They also serve as one of the most important messengers that may directly probe the properties of hot & dense matter in the interior region of core-collapse supernovae (CCSNe) and binary neutron star mergers.

In this talk, I will introduce our recent works that aim to constrain the properties of neutrino-dense matter reactions by using terrestrial nuclear experiments and ab-initial many-body calculations. Based on that, the influence of microscopic neutrino reactions on the explosion of CCSNe will be briefly discussed.  I will then discuss the multi-messenger analysis of CCSNe, where the neutrino and gravitational wave signals are jointly used to constrain the properties of asymmetric explosion and quark-hadron phase transitions that may appear in the inner region of CCSNe.
