"Neutrinos as Astrophysical Probes"

A long time ago, neutrinos were thought to be a handle to confirm our understanding of which processes are relevant in astrophysical sources. In particular, the first solar neutrino experiment was designed to confirm that nuclear reactions are the main source of energy in stars. The confirmation of which cycle is the dominant source of energy for the Sun needed 40 years of experimental effort; the discovery of neutrino oscillations was the reason for the delay. I will start by reviewing the most updated determination of neutrino masses and mixings. Then, I will concentrate on different astrophysical sources of neutrinos and our prospects on learning physics at the production, ranging from low energies, sub-MeV, to the highest energies, TeV and above.
