Description
The detection of neutrinos with energies above the TeV scale from astrophysical sources by neutrino telescopes has opened a new window for exploring the universe and testing the Standard Model at unprecedented energy scales. This talk will review recent observations from IceCube, including the detection of neutrinos from NGC 1068 and the more recent identification of neutrinos from the galactic plane, highlighting their implications for understanding neutrino properties across various scenarios. Given the long baselines and high energies of these neutrino events, we will focus on scenarios involving slow dynamical processes, which can significantly impact the observed neutrino signals.
