Description
Over a decade after the discovery of diffuse astrophysical neutrinos, the first evidence of individual neutrino sources has emerged. These sources exhibit several distinct characteristics: 1) they are powerful and abundant; 2) they are likely opaque to the gamma rays that accompany neutrino production; and 3) extragalactic neutrino emitters are significantly more powerful than Galactic ones. This presentation will explore the astrophysical environments that may produce the bulk of the diffuse neutrinos observed by IceCube, with a particular focus on active galactic nuclei. Additionally, we will discuss how recent observations of the neutrino emission from the Galactic Plane enhance our understanding of Galactic PeVatrons and their implications for future astroparticle studies at TeV-PeV energies.
