Title: High-Energy Neutrinos from the Milky Way and Beyond
Abstract:
The sky we know is largely written in light, but light tells only part of the story. Cosmic rays reach Earth with energies far beyond those produced by terrestrial accelerators, yet magnetic fields obscure where they came from. Neutrinos offer a different view: electrically neutral and weakly interacting, they can escape dense environments and travel across cosmic distances essentially undeflected, carrying information about where and how cosmic rays are accelerated.
I will discuss the emerging high-energy neutrino sky, beginning with the recent 5.7σ detection of neutrino emission from the Galactic plane and what it can tell us about cosmic-ray acceleration and propagation in the Milky Way. I will place these results in the broader multi-messenger picture, then move outward to the extragalactic neutrino sky and the ultra-high-energy frontier being explored by IceCube and KM3NeT. I will conclude with the prospects for the next generation of neutrino observatories and the continuing search for the sources of the highest-energy particles in the Universe.
