Deeper H.E.S.S. observations of Vela Junior (RX J0852.0-4622): morphology studies and resolved spectroscopy
(EDP Sciences, 2018)
Aims. We study γ-ray emission from the shell-type supernova remnant (SNR) RX J0852.0−4622 to better characterize its spectral properties and its distribution over the SNR.
Methods. The analysis of an extended High Energy ...
Discovery of the hard spectrum VHE γ-ray source HESS J1641-463
(IOP Publishing, 2014)
This Letter reports the discovery of a remarkably hard spectrum source, HESS J1641–463, by the High Energy Stereoscopic System (H.E.S.S.) in the very high energy (VHE) domain. HESS J1641–463 remained unnoticed by the usual ...
H.E.S.S. observations of RX J1713.7−3946 with improved angular and spectral resolution: evidence for gamma-ray emission extending beyond the X-ray emitting shell
(EDP Sciences, 2018)
Supernova remnants exhibit shock fronts (shells) that can accelerate charged particles up to very high energies. In the past decade, measurements of
a handful of shell-type supernova remnants in very high-energy gamma ...
Detailed spectral and morphological analysis of the shell type supernova remnant RCW 86
(EDP Sciences, 2018)
Aims. We aim for an understanding of the morphological and spectral properties of the supernova remnant RCW 86 and for insights into the
production mechanism leading to the RCW 86 very high-energy γ-ray emission.
Methods. ...
Characterising the VHE diffuse emission in the central 200 parsecs of our Galaxy with H.E.S.S.
(EDP Sciences, 2018)
The diffuse very high-energy (VHE; >100 GeV) γ-ray emission observed in the central 200 pc of the Milky Way by H.E.S.S. was found to follow dense matter distribution in the central molecular zone (CMZ) up to a longitudinal ...
HESS J1741-302: a hidden accelerator in the Galactic plane
(EDP Sciences, 2018)
The H.E.S.S. Collaboration has discovered a new very high energy (VHE, E > 0.1 TeV) γ-ray source, HESS J1741−302, located in the Galactic plane. Despite several attempts to constrain its nature, no plausible counterpart ...
Upper limits on very-high-energy gamma-ray emission from core-collapse supernovae observed with H.E.S.S.
(EDP Sciences, 2019)
Young core-collapse supernovae with dense-wind progenitors may be able to accelerate cosmic-ray hadrons beyond the knee of the cosmic-ray spectrum, and this may result in measurable gamma-ray emission. We searched for ...
