The spectrum of cosmic rays includes the most energetic particles ever observed. The mechanism of their acceleration and their sources are, however, still mostly unknown. Observing astrophysical neutrinos can help solve this problem. Because neutrinos are produced in hadronic interactions and are neither absorbed nor deflected, they point directly back to their source. Neutrinos may also be...

The IceCube Neutrino Observatory is a cubic-kilometre-scale neutrino telescope completed in the Austral summer of 2010/2011. The detector forms a lattice of 5,160 photomultiplier tubes (PMTs) installed in the South Polar ice cap at depths from 1450 to 2450 m. IceCube is designed to detect astrophysical neutrinos upward of 100 GeV and to study neutrino oscillations with atmospheric neutrinos...

The IceCube detector is designed to detect very high-energy neutrino events (exceeding 1 PeV) from astrophysical sources. DeepCore, a low-energy array, was designed to extend the reach of IceCube down to ~10 GeV. Data analyses at the low energies have unique challenges compared to their high-energy counterparts, including achieving robust reconstructions of the energy and angular properties...

Supernovae are the favoured location in the universe for certain processes necessary for the formation of heavy elements, and the only location where the effects of neutrino-neutrino scattering could plausibly be observed. This makes supernovae relevant to the fields of both nuclear astrophysics and particle physics.
A core collapse supernova can be detected by the immense burst of...

IceCube, the world’s largest neutrino detector, is designed to measure the highest energy neutrinos produced in astrophysical events. Augmented with a low-energy array, called DeepCore, IceCube has the ability to perform precision measurements of the high flux of atmospheric neutrinos for energies ranging from approximately 10 GeV to a few 100 TeV. When combined with the measurements by...
