TL;DR: The cosmic ray spectrum is measured using the two air-fluorescence detectors of the High Resolution Fly's Eye observatory operating in monocular mode to fit the spectrum to a model consisting of galactic and extragalactic sources.

TL;DR: A survey of Galactic gamma-ray sources at a median energy of ~20 TeV has been performed using the Milagro Gamma-Ray Observatory as mentioned in this paper, where the authors detected eight sources with pre-trial significances > 4.5 σ in the region of Galactic longitude l [30°, 220°] and latitude b [-10°, 10°].

TL;DR: In this article, a method to differentiate hadronic air showers from electromagnetic air showers in the Milagro gamma-ray observatory, based on the ability to detect the energetic particles in an extensive air shower, was used to detect TeV emission from the Crab Nebula.
