Acceleration of petaelectronvolt protons in the Galactic Centre

A. Abramowski, +229 more
- 24 Mar 2016 - 
TL;DR: Deep γ-ray observations with arcminute angular resolution of the region surrounding the Galactic Centre are reported, which show the expected tracer of the presence of petaelectronvolt protons within the central 10 parsecs of the Galaxy, and it is proposed that the supermassive black hole Sagittarius A* is linked to this PeVatron.
Journal ArticleDOI

Search for Photon-Linelike Signatures from Dark Matter Annihilations with H.E.S.S.

A. Abramowski, +208 more
TL;DR: In this paper, the authors obtained upper limits on line-like emission in the energy range between ~500 GeV and ~25 TeV for the central part of the Milky Way halo and for extragalactic observations, complementing recent limits obtained with the Fermi-LAT instrument at lower energies.
Journal ArticleDOI

Search for TeV Gamma-ray Emission from GRB 100621A, an extremely bright GRB in X-rays, with H.E.S.S

A. Abramowski, +214 more
TL;DR: In this paper, the authors show that the long gamma-ray burst (GRB) 100621A, at the time the brightest X-ray transient ever detected by Swift-XRT in the $0.3\textrm{--}10$ keV range, has been observed with the H.E.S. imaging air Cherenkov telescope array, sensitive to gamma radiation in the very high energy (VHE, $>100$ GeV) regime.
Journal ArticleDOI

Radio Imaging of the Very-High-Energy gamma-Ray Emission Region in the Central Engine of a Radio Galaxy

V. A. Acciari, +385 more
- 24 Jul 2009 - 
TL;DR: Radio and VHE observations of the radio galaxy Messier 87 are revealed, revealing a period of extremely strong VHE gamma-ray flares accompanied by a strong increase of theRadio flux from its nucleus, implying that charged particles are accelerated to very high energies in the immediate vicinity of the black hole.
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).
