Evidence for High-Energy Extraterrestrial Neutrinos at the IceCube Detector
TLDR
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.
Search for dark matter annihilations in the sun with the 79-string IceCube detector.
TLDR
A search for muon neutrinos from dark matter annihilation in the center of the Sun with the 79-string configuration of the IceCube neutrino telescope is performed, lowering the energy threshold and extending the search to the austral summer.
First observation of the Greisen-Zatsepin-Kuzmin suppression.
TLDR
High Resolution Fly's Eye's measurement of the flux of ultrahigh energy cosmic rays shows a sharp suppression at an energy of 6 x 10(19) eV, consistent with the expected cutoff energy.
First observation of PeV-energy neutrinos with IceCube.
TLDR
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.
Energy Reconstruction Methods in the IceCube Neutrino Telescope
Accurate measurement of neutrino energies is essential to many of the scientific goals of large-volume neutrino telescopes. The fundamental observable in such detectors is the Cherenkov light
Indications of proton-dominated cosmic-ray composition above 1.6 EeV.
TLDR
These measurements constrain models in which the galactic-to-extragalactic transition is the cause of the energy spectrum ankle at 4x10(18) eV, and are consistent with a predominantly protonic composition of cosmic rays when interpreted via the Q GSJET01 and QGSJET-II high-energy hadronic interaction models.
Limits on a muon flux from neutralino annihilations in the sun with the IceCube 22-string detector.
TLDR
Upper limits have been obtained on the annihilation rate of captured neutralinos in the Sun and converted to limits on the weakly interacting massive particle (WIMP) proton cross sections for WIMP masses in the range 250-5000 GeV.
Probing the origin of cosmic rays with extremely high energy neutrinos using the IceCube Observatory
We have searched for extremely high energy neutrinos using data taken with the IceCube detector between May 2010 and May 2012. Two neutrino-induced particle shower events with energies around 1 PeV
