TeV emission from the Galactic center strongly suggests the existence of a hadronic Pevatron located within ~10 pc of Sgr A*. If there is indeed a PeV proton/ion source and abundant molecular clouds in the surrounding, we expect several different observable effects such as multi-TeV neutrino, gamma-ray photons and electrons. In this presentation, I will discuss our efforts finding traces of...

Dozens of ultrahigh-energy gamma-ray sources have been detected to date. However, it remains largely unknown which of these sources accelerate hadronic cosmic rays and thus contribute to the mysterious cosmic-ray knee. High-energy neutrinos offer a unique and unambiguous probe of hadronic PeVatrons, as they are most likely produced through interactions of hadronic cosmic rays. In this talk, I...

Neutrino astronomy is starting to unveil new features of the extreme non-thermal Universe, thanks to the operation of several large volume Cherenkov neutrino telescopes, as IceCube, Baikal-GVD, and KM3NeT. These instruments benefit of extended and complementary fields of view, coupled to high duty cycle and sub-degree angular resolution, allowing the study of cosmic neutrinos and their...
