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: The combined gamma-ray image of the 2004 and 2005 data reveals the morphology of RX J1713.7-3946 with unprecedented precision, as well as significantly increased statistics and energy coverage as compared to earlier 2003 & 2004 results.

TL;DR: The W28 field was observed at Very High Energy (VHE) gamma-ray energies (E>0.1 TeV) with the H.E.S. Cherenkov telescopes to indicate a hadronic origin for HESSJ1801-233 and HessJ1800-240, and several cloud components in projection may contribute to the VHE emission.
