TL;DR: In this paper, the authors reported the first observation of an anisotropy in the arrival direction of cosmic rays with energies in the multi-TeV region in the Southern sky using data from the IceCube detector.

TL;DR: In this article, the results and methodology of a search for neutrinos produced in the decay of charged pions created in interactions between protons and gamma-rays during the prompt emission of 807 gamma-ray bursts (GRBs) over the entire sky were presented.

TL;DR: In this paper, a power spectrum analysis was performed on the relative intensity map of the cosmic ray flux in the southern hemisphere, and it was shown that the arrival direction distribution is not isotropic, but shows significant structure on several angular scales.

TL;DR: In this article, a real-time analysis framework for the IceCube neutrino observatory has been implemented, aiming for the identification of an electromagnetic counterpart of a rapidly fading source, and the first realtime analyses to be activated within this framework, highlights their sensitivities to astrophysical neutrinos and background event rates, and presents an outlook for future discoveries.

TL;DR: In this article, the authors relax the hypothesis that the fluctuation spectrum can be described by a single power law, and demonstrate that an Einstein-de Sitter universe with zero cosmological constant can fit the data as well as the best concordance model.
