The Large Area Telescope on the Fermi Gamma-ray Space Telescope Mission

W. B. Atwood, +292 more
TL;DR: The Large Area Telescope (Fermi/LAT) as mentioned in this paper is the primary instrument on the Fermi Gamma-ray Space Telescope, which is an imaging, wide field-of-view, high-energy gamma-ray telescope, covering the energy range from below 20 MeV to more than 300 GeV.
Journal ArticleDOI

Fermi Large Area Telescope Second Source Catalog

P. L. Nolan, +293 more
TL;DR: The second Fermi-LAT catalog (2FGL) as mentioned in this paper includes source location regions, defined in terms of elliptical fits to the 95% confidence regions and spectral fits in terms either power-law, exponentially cutoff power law, or log-normal forms.
Journal ArticleDOI

Evidence for High-Energy Extraterrestrial Neutrinos at the IceCube Detector

M. G. Aartsen, +96 more
- 20 Nov 2013 - 
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.
Journal ArticleDOI

Fermi large area telescope first source catalog

A. A. Abdo, +288 more
TL;DR: The first Fermi-LAT catalog (1FGL) as mentioned in this paper contains 1451 sources detected and characterized in the 100 MeV to 100 GeV range, and the threshold likelihood Test Statistic is 25, corresponding to a significance of just over 4 sigma.
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.
