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: Limits are derived on the velocity-weighted annihilation cross section (σv) as a function of the DM particle mass that are among the best reported so far for this energy range and in particular differ only little between the chosen density profile parametrizations.
