Modelling the transport of cosmic rays (CRs) in the heliosphere represents a global
challenge in the field of heliophysics, in that such a study, if it were to be performed from first …

This paper reviews three important effects on energetic particles of corotating interaction
regions (CIRs) in the solar wind that are formed at the leading edges of high-speed solar …

The last solar minimum activity period, and the consequent minimum modulation conditions
for cosmic rays, was unusual. The highest levels of galactic protons were recorded at Earth …

The combined influence of stellar energetic particles and galactic cosmic rays (GCRs) on the
radiation environment, and hence potential habitability, of Earth-like exoplanets is relatively …

Recent advances in the detection of cosmic-ray (CR) antiproton intensities at Earth have the
potential to provide valuable new insights in the search for dark matter. As such, a fuller …

ABSTRACT A time-dependent model based on a numerical solution of Parker's transport
equation is used to model the modulation of cosmic-ray protons, electrons, and helium for …

We present a newly developed numerical modulation model to study the transport of galactic
and Jovian electrons in the heliosphere. The model employs stochastic differential …

The Ulysses spacecraft has been the first to orbit the Sun over its poles and to explore the
heliosphere at these high heliolatitudes. It has now completed two fast latitude scans, one at …

The ratio of the luminosity of diffuse 511 keV positron annihilation radiation, measured by
INTEGRAL in its four years, from a Galactic" positron bulge"(< 1.5 kpc) compared to that of …

ABSTRACT A propagation model of galactic cosmic protons through the heliosphere was
implemented using a two-dimensional Monte Carlo approach to determine the differential …
