Discovery of VHE y-rays from the BL Lacertae object PKS 0548-322
(EDP Sciences, 2010)
Aims. PKS 0548-322 (z=0.069) is a "high-frequency-peaked'' BL Lac object and a candidate very high energy (VHE, E >100 GeV) $\gamma$-ray emitter, due to its high X-ray and radio flux. Observations at the VHE band provide ...
First detection of VHE y-rays from SN 1006 by HESS
(EDP Sciences, 2010)
Localizing the VHE y-ray source at the galactic centre
(Oxford University Press, 2010)
The inner 10 pc of our Galaxy contains many counterpart candidates of the very high energy (VHE; >100 GeV) γ -ray point source HESS J1745−290. Within the point spread function of the H.E.S.S. measurement, at least three ...
Numerical simulations of composite supernova remnants for small σ pulsar wind nebulae
(EDP Sciences, 2013)
Context. Composite supernova remnants consist of a pulsar wind nebula located inside a shell-type remnant. The presence of a shell has implications on the evolution of the nebula, although the converse is generally not ...
HESS upper limit on the very high energy gammay-ray emission from the globular cluster 47 Tucanae (Research Note)
(EDP sciences, 2009)
Observations of the globular cluster 47 Tucanae (NGC 104), which contains at least 23 ms pulsars, were performed with the HESS telescope system. The observations lead to an upper limit of F(E > 800 GeV) < 6.7 × 10−13 cm−2 ...
Energy spectrum of cosmic-ray electrons at TeV energies
(The American Physical Society, 2008)
The very large collection area of ground-based γ-ray telescopes gives them a substantial advantage over balloon or satellite based instruments in the detection of very-high-energy (>600 GeV) cosmic-ray electrons. Here we ...
Discovery of VHE emission towards the carina arm region with the H.E.S.S. telescope array: HESS J1018-589
(EDP Science, 2012)
The Carina arm region, containing the supernova remnant SNR G284.3–1.8, the high-energy (HE; E > 100 MeV) binary 1FGL J1018.6–5856 and the energetic pulsar PSR J1016–5857 and its nebula, has been observed with the H.E.S.S. ...
Discovery of very high energy y-ray emission from Centaurus A with HESS.
(IOP Publishing Limited, 2009)
We report the discovery of faint very high energy (VHE; E > 100 GeV) γ-ray emission from the radio galaxy Centaurus A in observations performed with the High Energy Stereoscopic System (H.E.S.S.) experiment, an imaging ...
Discovery of VHE gamma-rays from the high-frequency-peaked BL Lacertae object RGB J0152+017
(EDP sciences, 2008)
Aims. The BL Lac object RGB J0152+017 (z=0.080) was predicted to be a very high-energy (VHE; >100 GeV) $\gamma$-ray source, due to its high X-ray and radio fluxes. Our aim is to understand the radiative processes by ...
