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

New constraints on the mid-IR EBL from the HESS discovery of VHE gamma-rays from 1ES 0229+200

Felix Aharonian, +143 more
TL;DR: In this paper, a very high energy (VHE: >100 GeV) γ-ray emission from the high-frequency peaked BL Lac 1ES 0229+200 was detected at the 6.6σ level in the HESS observations (41.8 h live time).
Journal ArticleDOI

The 2010 very high energy gamma-ray flare and 10 years of multi-wavelength observations of M 87

A. Abramowski, +453 more
TL;DR: The long-term multi-wavelength light curve of M 87, spanning from radio to VHE and including data from Hubble Space Telescope, Liverpool Telescope, Very Large Array, and European VLBI Network, is used to further investigate the origin of the VHE gamma-ray emission.
Journal ArticleDOI

First detection of VHE gamma-rays from SN 1006 by H.E.S.S

Fabio Acero, +176 more
TL;DR: In this paper, a very high energy (VHE) gamma-ray signal was detected from SN 1006, which is consistent with the previously established H.E.S. upper limit, thus motivating further in-depth observations of this source.
