Core-collapse supernovae - ideal physics laboratories

Core-collapse supernovae are one of the most fascinating and mysterious phenomena in the universe. These dramatic explosions of dying stars are also powerful sources of neutrinos, the most elusive particles known. Detection of supernova neutrinos offers a unique opportunity to explore physics in extreme conditions not accessible on Earth. However, despite the detection of about twenty electron antineutrinos from SN 1987 A, we are yet to test even the most fundamental prediction about the neutrino emission, namely that different neutrino flavors share a comparable amount of the released energy during the collapse. To address this challenge, existing and upcoming neutrino detectors offer the potential to register significantly more neutrinos of all flavors from the next nearby core-collapse supernova. In this talk will showcase how the upcoming measurements of galactic supernova neutrinos and the diffuse supernova neutrino background can provide invaluable insights into the physics of core-collapse supernovae and physics byond the Standard Model, allowing us to push the frontiers of astrophysics and particle physics further.
