Extended VHE γ-ray emission towards SGR1806-20, LBV 1806-20, and stellar cluster Cl 1806-20
(EDP Sciences, 2018)
Using the High Energy Spectroscopic System (H.E.S.S.) telescopes we have discovered a steady and extended very high-energy (VHE) γ-ray source towards the luminous blue variable candidate LBV 1806−20, massive stellar cluster ...
The population of TeV pulsar wind nebulae in the H.E.S.S. Galactic Plane Survey
(EDP Sciences, 2018)
The nine-year H.E.S.S. Galactic Plane Survey (HGPS) has yielded the most uniform observation scan of the inner Milky Way in the TeV gamma-ray band to date. The sky maps and source catalogue of the HGPS allow for a systematic ...
The supernova remnant W49B as seen with H.E.S.S. and Fermi-LAT
(EDP Sciences, 2018)
The supernova remnant (SNR) W49B originated from a core-collapse supernova that occurred between one and four thousand years ago, and subsequently evolved into a mixed-morphology remnant, which is interacting with molecular ...
A search for very high-energy flares from the microquasars GRS 1915+105, Circinus X-1, and V4641 Sgr using contemporaneous H.E.S.S. and RXTE observations
(EDP Sciences, 2018)
Context. Microquasars are potential γ-ray emitters. Indications of transient episodes of γ-ray emission were recently reported in at least two systems: Cyg X-1 and Cyg X-3. The identification of additional γ-ray-emitting ...
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 ...
Constraints on particle acceleration in SS433/W50 from MAGIC and H.E.S.S. observations
(EDP Sciences, 2018)
Context. The large jet kinetic power and non-thermal processes occurring in the microquasar SS 433 make this source a good candidate for a very high-energy (VHE) gamma-ray emitter. Gamma-ray fluxes above the sensitivity ...
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 ...
Population study of Galactic supernova remnants at very high γ-ray energies with H.E.S.S.
(EDP Sciences, 2018)
Shell-type supernova remnants (SNRs) are considered prime candidates for the acceleration of Galactic cosmic rays (CRs) up to the knee of the CR spectrum at E ≈ 3 × 1015 eV. Our Milky Way galaxy hosts more than 350 SNRs ...
