# Towards an anagraphical picture of high-energy Galactic neutrinos

## TL;DR

This paper reviews the current understanding of high-energy Galactic neutrinos, focusing on their origins, observational limits, and the implications for cosmic-ray sources and propagation models.

## Contribution

It provides an overview of recent observational constraints and discusses the implications for the nature and activity duration of Galactic neutrino sources.

## Key findings

- No point-like Galactic neutrino excess observed
- Upper limits set by IceCube, ANTARES, HAWC, and Fermi-LAT
- Short-lived PeV hadronic activity likely responsible for neutrino production

## Abstract

The TeV/PeV neutrino emission from our Galaxy is related to the distribution of cosmic-ray accelerators, their maximal energy of injection as well as the propagation of injected particles and their interaction with molecular gas. In the last years Interesting upper limits on the diffuse hadronic emission from the whole Galaxy, massive molecular clouds and Fermi Bubbles were set by the IceCube and ANTARES as well as HAWC and Fermi-LAT observations. On the other hand no evidence of Galactic point-like excess has been observed up to now by high-energy neutrino telescopes. This result can be related to the short duration of the PeV hadronic activity of the sources responsible for the acceleration of primary protons, possibly including supernova remnants. All these aspects will be discussed in this work.
