The American Physical Society meeting on astronomy, astrophysics, cosmology and particle physics, the so-called April meeting, closes today in Washington DC. The IceCube Collaboration has presented brand new results on neutrino oscillations that are comparable in precision to long-baseline neutrino experiments. From WIPAC, many PhD students and more senior staff presented results about IceCube, including the masterclass, along with results on CTA and Fermi.

Decades ago, the aspiration to build a kilometer-scale neutrino detector at the South Pole seemed farfetched; today, we celebrate the 5-year anniversary of this incredible achievement.

IceCube data are stubbornly showing us only a glimpse of the extreme universe at a time. Ever since the discovery of a flux of TeV-PeV astrophysical neutrinos, scientists have been studying various potential sources of these neutrinos, and little by little, learning details about the composition of the cosmic neutrino flux.

Sorting through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year, researchers using the IceCube Neutrino Observatory have gathered powerful new evidence in support of 2013 observations confirming the existence of cosmic neutrinos.

Prof. Olga Botner, IceCube spokesperson and a physics professor at the University of Uppsala, and Prof. Francis Halzen, IceCube principal investigator and a professor at the University of Wisconsin–Madison, tell us about the plans for an upgrade to the IceCube Neutrino Observatory.

How is it possible to distinguish a neutrino produced by the interaction of cosmic rays in the Earth’s atmosphere from an astrophysical neutrino when the particles themselves are identical? The idea is simple enough: atmospheric neutrinos are always produced together with other particles, including muons.

A few years after the completion of IceCube, one of the major goals of building this strange cubic-kilometer detector at the South Pole has already been accomplished: the unequivocal observation of an astrophysical neutrino flux.
