The millisecond pulsar contribution to the rising positron fraction
Christo Venter, Andreas Kopp, Alice K Harding +2
Pair cascades from millisecond pulsars (MSPs) may be a primary source of Galactic electrons and positrons that contribute to the increase in positron flux above 10 GeV as observed…
Glow-in-the-dark globular clusters: modelling their multiwavelength lanterns
C. Venter, I. Buesching, A. Kopp +2
Globular clusters (GCs) are astronomical tapestries embroidered with an abundance of exotic stellar-type objects. Their high age promises a rich harvest of evolved stellar products…
Modelling the stellar soft-photon energy density profile of globular clusters
P L Prinsloo, C Venter, I Büsching +1
Recent observations by the Fermi Large Area Telescope (LAT) and the High Energy Stereoscopic System (H.E.S.S.) have revealed globular clusters (GC) to be sources of high-energy (HE…
Multiwavelength Modelling of the Globular Cluster Terzan 5
I. Buesching, C. Venter, A. Kopp +2
Diffuse X-ray emission has recently been detected from the globular cluster (GC) Terzan 5, extending out to ~2.5' from the cluster centre. This emission may arise from synchrotron…
Constraints on the gamma-ray emission from the cluster-scale AGN outburst in the Hydra A galaxy cluster
HESS Collaboration, A. Abramowski, F. Acero +193
In some galaxy clusters powerful AGN have blown bubbles with cluster scale extent into the ambient medium. The main pressure support of these bubbles is not known to date, but cosm…
Multi-wavelength Observations of H 2356-309
HESS Collaboration, A. Abramowski, F. Acero +184
AIMS: The properties of the broad-band emission from the high-frequency peaked BL Lac H 2356-309 (z=0.165) are investigated. METHODS: Very High Energy (VHE; E > 100 GeV) observatio…
Cosmic-ray propagation properties for an origin in SNRs
I. Buesching, A. Kopp, M. Pohl +3
We have studied the impact of cosmic-ray acceleration in SNR on the spectra of cosmic-ray nuclei in the Galaxy using a series expansion of the propagation equation, which allows us…
