Modelling anomalous cosmic ray oxygen in the heliosheath
(EDP Sciences, 2010)
This paper discusses a numerical modulation model to describe anomalous cosmic ray acceleration and transport in the heliosheath, the portion of the heliosphere between the termination shock and the heliopause. The model ...
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 ...
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.)

Primary particle acceleration above 100 TeV in the shell-type supernova remnant RX J1713.7-3946 with deep H.E.S.S. observations (Corrigendum)
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 ...
Cosmic-ray acceleration and escape from post-adiabatic supernova remnants
(EDP Sciences, 2020)
Context. Supernova remnants are known to accelerate cosmic rays on account of their nonthermal emission of radio waves, X-rays,
and gamma rays. Although there are many models for the acceleration of cosmic rays in supernova ...
The re-acceleration of galactic electrons at the heliospheric termination shock
(IOP Publishing, 2017)
Observations by the Voyager spacecraft in the outer heliosphere presented several challenges for the paradigm of diffusive shock acceleration (DSA) at the solar wind termination shock (TS). In this study, the viability of ...
The heliospheric transport and modulation of multiple charged anomalous oxygen revisited
(EDP Sciences, 2010)
Context. Since the crossings of the solar wind termination shock by the Voyager 1 and 2 spacecraft, much speculation has surrounded the acceleration mechanism and region where the anomalous cosmic ray component is accelerated. ...
Are anomalous cosmic rays the main contribution to the low-energy galactic cosmic ray spectrum?
(IOP Publishing, 2008)
While the high-energy part of the Galactic cosmic ray spectrum is well observed, its nature at energies below
about 1 GeV nucleon-1 is still not known well. Recent in situ measurements made with the Voyager 1 spacecraft
in ...
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 ...
