Neutrino Astrophysics with JUNO

The Jiangmen Underground Neutrino Observatory will aim for the determination of the neutrino mass hierarchy with a medium baseline reactor $\overline{\nu}_e$ oscillation experiment. With its 20\,kt liquid scintillator detector, it will also be sensitive to astrophysical low-energy neutrinos. In case of a typical galactic core-collapse supernova, $\sim5000$ neutrino interactions will be detected via the inverse beta decay alone. Moreover, a $3\sigma$ evidence for the diffuse supernova neutrino background seems within reach after ten years of measurement. The performance of the experiment's solar neutrino program will decisively depend on the achieved radiopurity and cosmogenic background rejection efficiency
