Discovery of very-high-energy gamma-ray emission from the vicinity of PSR J1913+1011 with HESS
(EDP Sciences, 2008)
The HESS experiment, an array of four Imaging Atmospheric Cherenkov Telescopes with high sensitivity and large field-of-view, has been used to search for emitters of very-high-energy (VHE, >100 GeV) $\gamma$-rays along the ...
The role of radial perpendicular diffusion and latitude dependent acceleration along the solar
(Elsevier, 2008)
A numerical model, based on Parker’s transport equation, describing the modulation of anomalous cosmic rays and containing diffusive shock acceleration is applied. The role of radial perpendicular diffusion at the solar ...
Constraints on the multi-TeV particle population in the Coma galaxy cluster with HESS observations
(EDP Sciences, 2009)
Aims. Galaxy clusters are key targets in the search for ultra high energy particle accelerators. The Coma cluster represents one of the best candidates for such a search owing to its high mass, proximity, and the established ...

Die skoenlusmetode: 'n kritiese oorsig
(AOSIS, 2008)
Sedert die ontstaan van die skoenlusmetodologie, het dit beide 'n kragtige versameling oplossings gebied vir die praktiese gebruiker van statistiek , sowel as 'n ryk bron van teoretiese en metodologiese oplossings vir ...

Cosmic ray flux at the earth in a variable heliosphere
(Elsevier, 2008)
In recent years the variability of the cosmic ray flux has become one of the main issues not only for the interpretation of the abundances of cosmogenic isotopes in cosmochronic archives like, e.g., ice cores, but also for ...
