Opening a new window onto the universe with IceCube

TL;DR: In this article, the authors present an overview of a next-generation instrument, IceCube-Gen2, which will sharpen our understanding of the processes and environments that govern the Universe at the highest energies.

TL;DR: Fusco et al. as discussed by the authors used machine learning techniques applied to 10 years of data from the IceCube Neutrino Observatory to identify neutrino emission from the Galactic plane at the 4.5σ level of significance, which is consistent with diffuse emission of neutrinos from the Milky Way but could also arise from a population of unresolved point sources.

TL;DR: In this article, the authors review the important progress made in recent years towards understanding the experimental data on ultra-high-energy (E ≳ 1 0 9 GeV ) cosmic rays.

TL;DR: High-energy astrophysical muon–neutrino flux measurement with 9.5 years of IceCube data. Improved characterization of the flux with increased event sample and extended model testing.

TL;DR: The presence of a high-energy neutrino flux containing the most energetic neutrinos ever observed is revealed, including 28 events at energies between 30 and 1200 TeV, although the origin of this flux is unknown and the findings are consistent with expectations for a neutRino population with origins outside the solar system.

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.

TL;DR: In this paper, it was shown that a large fraction of the energy of a relativistic fireball energy can be converted by photomeson production to a burst of neutrinos.

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.
