IceCube Observatory: Neutrinos and the Origin of Cosmic Rays
Paolo Desiati (for the IceCube Collaboration)
TL;DR
The IceCube Observatory is a large neutrino detector providing crucial limits on high-energy cosmic neutrinos, impacting our understanding of cosmic ray origins and revealing anisotropies in cosmic ray distribution.
Contribution
This paper reviews the current status of astrophysical neutrino searches and the observation of cosmic ray anisotropy using the IceCube Observatory.
Findings
Stringent limits on high-energy cosmic neutrino fluxes.
Non-detection constrains models of cosmic ray origins.
Observation of persistent cosmic ray anisotropy above 100 TeV.
Abstract
The completed IceCube Observatory, the first km^3 neutrino telescope, is already providing the most stringent limits on the flux of high energy cosmic neutrinos from point-like and diffuse galactic and extra-galactic sources. The non-detection of extra-terrestrial neutrinos has important consequences on the origin of the cosmic rays. Here the current status of astrophysical neutrino searches, and of the observation of a persistent cosmic ray anisotropy above 100 TeV, are reviewed.
