Description

The origin of a majority of the isotropic flux of astrophysical neutrinos observed by the IceCube Neutrino Observatory remains an open question. The Galactic plane, due to its proximity, and the abundance of multi-wavelength information is a suitable place to study potential cosmic-ray acceleration sites. Recent gamma-ray observations by HAWC and LHAASO have presented evidence for multiple galactic sources that exhibit a spatially extended morphology and have energy spectra continuing beyond 100 TeV. A fraction of such emission could be produced by hadronic cosmic-ray acceleration in these regions. Observation of a neutrino source from the Galactic plane would be the smoking gun for the presence of a nearby PeVatron. Using 10 years of data comprising muon-neutrino tracks, we perform a dedicated search for extended neutrino sources in the Galaxy. We present our results and discuss the prospects for Galactic neutrino astronomy using multi-messenger data.
