Description
Supernova remnants (SNRs) are believed to be a prominent engine for accelerating nuclei to produce cosmic rays. When these accelerated nuclei interact with stationary protons, they can produce charged pions, which decay into charged leptons and neutrinos. Because the neutrino emission can be directly traced back to the SNR source, comparisons between the neutrino and photon fluxes offer an avenue to probe the acceleration mechanism of cosmic rays by SNRs. We present on efforts to produce self-consistent predictions for the emission of neutrinos and photons throughout the lifetime of an SNR, and comparison between the neutrino emission spectra from realistic models of SNRs and IceCube and IceCube Gen2 (projected) sensitivities.
