TL;DR: In this measurement, the first of this type, the High Energy Stereoscopic System is able to extend the measurement of the electron spectrum beyond the range accessible to direct measurements, finding evidence for a substantial steepening in the energy spectrum above 600 GeV compared to lower energies.

TL;DR: In this article, the authors present a measurement of the cosmic-ray electron spectrum with H.E.S. starting at 340 GeV and show no indication of a structure in the electron spectrum, but rather a power-law spectrum with spectral index of 3.0 +- 0.1 (stat.) + − 0.3 (syst.) which steepens at about 1 TeV.

TL;DR: In this paper, the authors used the observed VHE spectrum to derive limits on the Extragalactic Background Light (EBL) and determined physical quantities through the modeling of the object's broad-band spectral energy distribution (SED).
