Description
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 will present observations of the Galactic plane using neutrinos detected by the IceCube Observatory. I will also explore theoretical interpretations that shed light on these findings and discuss their broader implications for our understanding of Galactic PeVatrons
