Neutrinos in supernovae

Abstract: Core-collapse supernovae originate from the gravitational collapse of massive stars. These explosions are the birthplace of neutron stars, the site of element synthesis, and the source of copious quantities of neutrinos. Numerical simulations of core-collapse supernovae are a challenging and computationally expensive problem. Due to this, approximations are made (e.g. in the neutrino transport) or some aspects (eg nucleosynthesis or neutrino flavor oscillations) are addressed in a post-processing approach instead of being self-consistently included in the hydrodynamical simulations. In this talk, I will discuss recent results on supernovae and neutrinos from our group. I will present the first hydrodynamic core-collapse supernova simulation which simultaneously includes flavor transformation of the free-streaming neutrinos in the neutrino transport. I will also present multi-messenger signals from a large set of core-collapse supernova simulations. And I will conclude by discussing the neutrino signal from a less common type of supernovae, the pair-instability supernovae.
