Description

Galactic PeVatrons - the accelerators of PeV cosmic rays - remain unidentified. Observations by LHAASO, HAWC and HESS of >100 TeV γ-ray emission have revealed promising candidates, but γ-rays alone can't distinguish hadronic from leptonic processes. We report a search for neutrino counterparts to the extended Cygnus Cocoon region and to PeVatron candidates using ICEMAN, the 12.3-year IceCube Multi-Flavor Astrophysical Neutrino sample - an all-sky dataset that combines starting tracks, through-going muons and cascade events.
