An Exceptional Very High Energy Gamma-Ray Flare of PKS 2155-304

Felix Aharonian, +125 more
TL;DR: In this paper, the average flux observed during an extreme gamma-ray outburst is I(>200 GeV) = (1.72$\pm$$0.05_{\rm stat}
Journal ArticleDOI

Energy Spectrum of Cosmic-Ray Electrons at TeV Energies

Felix Aharonian, +155 more
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.
Journal ArticleDOI

Probing the ATIC peak in the cosmic-ray electron spectrum with H.E.S.S.

Felix Aharonian, +168 more
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.
Journal ArticleDOI

Fast variability of tera-electron volt gamma rays from the radio galaxy M87.

Felix Aharonian, +128 more
- 01 Dec 2006 - 
TL;DR: The detection of fast variations of the TeV (10^12 eV) gamma-ray flux, on time-scales of days, from the nearby radio galaxy M 87 is reported in this article.
Journal ArticleDOI

Primary particle acceleration above 100 TeV in the shell-type supernova remnant RX J1713.7-3946 with deep HESS observations

Felix Aharonian, +124 more
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.
