Journal ArticleDOI

Observation of high-energy astrophysical neutrinos in three years of icecube data

M. G. Aartsen, +302 more
TL;DR: Results from an analysis with a third year of data from the complete IceCube detector are consistent with the previously reported astrophysical flux in the 100 TeV-PeV range at the level of 10(-8) GeV cm-2 s-1 sr-1 per flavor and reject a purely atmospheric explanation for the combined three-year data at 5.7σ.
Journal ArticleDOI

First observation of PeV-energy neutrinos with IceCube

M. G. Aartsen, +287 more
TL;DR: These two neutrino-induced events could be a first indication of an astrophysical neutrinos flux; the moderate significance, however, does not permit a definitive conclusion at this time.
Journal ArticleDOI

Neutrino emission from the direction of the blazar TXS 0506+056 prior to the IceCube-170922A alert

M. G. Aartsen, +329 more
- 13 Jul 2018 - 
TL;DR: In this article, a high-energy neutrino event detected by IceCube on 22 September 2017 was coincident in direction and time with a gamma-ray flare from the blazar TXS 0506+056.
Journal ArticleDOI

Optical properties of deep glacial ice at the South Pole

Markus Ackermann, +116 more
TL;DR: In this article, the authors used pulsed and continuous light sources embedded with the AMANDA neutrino telescope, an array of more than six hundred photomultiplier tubes buried deep in the ice.
