ISM: cosmic rays — ISM: supernova remnants — magnetohydrodynamics (MHD) — shock waves

Introduction
============

Gamma-ray observations with both space- and ground-based telescopes have shown that supernova remnants are the main sources of CRs at least up to 100 TeV. Galactic sources of PeV CRs, however, are still to be identified [see e.g. @blandford14; @amato14] although it has been argued that type IIb supernovae, a subclass which comprise about 3% of the observed core collapse SNe, may be able to produce CRs with energies beyond 100 PeV [e.g., @ptu10]. Cosmic neutrino observations are well suited for identifying galactic [pevatrons]{}[see e.g. @HH02; @aharonian04; @Becker08; @pevatrons14]. The (IceCube) has detected 37 neutrino events above the expected atmospheric neutrino background in a 988-day sample [@Aartsen14], with three PeV neutrinos, $1.041^ {+132}_{-144}$ PeV, $1.141^{+143}_{-133}$ PeV and $2.004^{+236}_{-262}$ PeV, being the most energetic neutrino events in history. While significant spatial or time clustering of the events has not yet been reported, a possible association of some events with galactic center sources was proposed [e.g., @Razzaque13].

The [*ANTARES*]{} neutrino telescope [@ANTARES_GC_14], using six years of data collected near the galactic centre, reported 90% confidence level upper limits on the muon neutrino flux to be between 3.5
