Cosmic-ray positrons from millisecond pulsars
(IOP Publishing, 2015)
Observations by the Fermi Large Area Telescope of γ-ray millisecond pulsar (MSP) light curves imply copious pair
production in their magnetospheres, and not exclusively in those of younger pulsars. Such pair cascades may ...
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 ...
A search for new supernova remnant shells in the Galactic plane with H.E.S.S.
(EDP Sciences, 2018)
A search for new supernova remnants (SNRs) has been conducted using TeV γ-ray data from the H.E.S.S. Galactic plane survey. As an identification criterion, shell morphologies that are characteristic for known resolved TeV ...
Primary particle acceleration above 100 TeV in the shell-type supernova remnant RX J1713.7-3946 with deep H.E.S.S. observations (Corrigendum to article: Primary particle acceleration above 100 TeV in the shell-type supernova remnant RX J1713.7-3946 with deep HESS observations, 464(1):235-243.)
(EDP Sciences, 2011)
Primary particle acceleration above 100 TeV in the shell-type supernova remnant RX J1713.7-3946 with deep H.E.S.S. observations (Corrigendum)
A new SNR with TeV shell-type morphology: HESS J1731-347
(EDP Sciences, 2011)
Aims. The recent discovery of the radio shell-type supernova remnant (SNR), G353.6-0.7, in spatial coincidence with the unidentified TeV source HESS J1731−347 has motivated further observations of the source with the High ...
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 ...
Observations of the Large Magellanic Cloud with Fermi
(EDP Sciences, 2010)
Context. The Large Magellanic Cloud (LMC) is to date the only normal external galaxy that has been detected in high-energy gamma rays. Highenergy
gamma rays trace particle acceleration processes and gamma-ray observations ...
