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 ...
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 ...
Extracting the ground level enhancement event of February 1956 from Legacy cosmic ray recordings
(IEEE, 2018)
Early continuous recordings of cosmic rays, as measured with Carnegie Type C Ionization Chambers, were made on rolls of photographic paper. This paper describes the extraction of the ionization data of a ground level ...
A study of Electron Forbush decreases with a 3D SDE numerical model
(IOP Publishing, 2018)
Because of the precise measurements of the cosmic ray electron flux by the PAMELA and AMS02, Electron Forbush decreases (Fds) have recently been observed for the first time. This serves as motivation to perform a numerical ...
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 ...
Energy spectra of carbon and oxygen with HELIOS E6: radial gradients of anomalous cosmic ray oxygen within 1 AU
(EDP Sciences, 2018)
Context. Anomalous cosmic rays (ACRs) are well-suited to probe the transport conditions of cosmic rays in the inner heliosphere.We
revisit the HELIOS data not only in view of the upcoming Solar Orbiter experiment but also ...
Proton fluxes measured by the PAMELA experiment from the minimum to the maximum solar activity for solar cycle 24
(IOP Publishing, 2018)
Precise measurements of the time-dependent intensity of the low-energy (<50 GeV) galactic cosmic rays (GCRs)
are fundamental to test and improve the models that describe their propagation inside the heliosphere. In ...
A simplified ab initio cosmic-ray modulation model with simulated time dependence and predictive capability
(IOP Publishing, 2018)
A simplified ab initio approach is followed to model cosmic-ray proton modulation, using a steady-state three-dimensional stochastic solver of the Parker transport equation that simulates some effects of time dependence. ...
