Description
Over the past decade, neutrino astronomy has evolved into a precision tool for probing the high-energy universe. Here we present an updated characterization of the extragalactic diffuse neutrino flux measured by the IceCube Neutrino Observatory, spanning energies from a few TeV to beyond 10 PeV. Using ten years of full-sky data, we identify the first Glashow-resonance candidate — an electron antineutrino interacting via on-shell W- decay. We also report IceCube’s most precise flavour ratio measurements to date, including the identification of high-energy tau neutrino candidates. In addition, we observe a possible deviation from a single power-law in the diffuse flux, suggesting curvature or a spectral break near a few tens of TeV.
