PKS 2005-489 at VHE: four years of monitoring with HESS and simultaneous multi-wavelength observations
(EDP Sciences, 2010)
Aims. Our aim is to study the very high energy (VHE; E>100 GeV) γ-ray emission from BL Lac objects and the evolution in time of their broad-band spectral energy distribution (SED).
Methods. VHE observations of the ...
Spatially resolved XMM-Newton analysis and a model of the nonthermal emission of MSH 15-52
(EDP Sciences, 2010)

First detection of VHE y-rays from SN 1006 by HESS
(EDP Sciences, 2010)
Aims. Recent theoretical predictions of the lowest very high energy (VHE) luminosity of SN 1006 are only a factor 5 below the previously published HESS upper limit, thus motivating further in-depth observations of this ...
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 ...
Discovery of extended VHE Y-ray emission from the vicinity of the young massive stellar cluster Westerlund 1
(EDP Sciences, 2012)
Aims. Results obtained in very-high-energy (VHE; E≥100GeV) γ-ray observations performed with the H.E.S.S. telescope array are used to investigate particle acceleration processes in the vicinity of the young massive stellar ...
Discovery of VHE emission towards the Carina arm region with the H.E.S.S. telescope array: HESS J1018-589
(EDP Sciences, 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 gamma-ray emission from the extragalactic pulsar wind nebula N 157B with H.E.S.S
(EDP Sciences, 2012)
We present the significant detection of the first extragalactic pulsar wind nebula (PWN) detected in gamma rays, N 157B, located in the large Magellanic Cloud (LMC). Pulsars with high spin-down luminosity are found to power ...
The 2010 very high energy γ-ray flare and 10 years of multi-wavelength observations of M 87
(IOP Publishing, 2012)
The giant radio galaxy M 87 with its proximity (16 Mpc), famous jet, and very massive black hole ((3 – 6) × 109 M☉) provides a unique opportunity to investigate the origin of very high energy (VHE; E > 100 GeV) γ-ray ...
Discovery of hard-spectrum y-ray emission from the BL Lacertae object 1ES 0414+009
(EDP Sciences, 2012)
Context. 1ES 0414 + 009 (z = 0.287) is a distant high-frequency-peaked BL Lac object, and has long been considered a likely emitter of very-high-energy (VHE, E > 100 GeV) γ-rays due to its high X-ray and radio flux.
Aims. ...
