Solar energetic particles, or SEPs, from suprathermal (few keV) up to relativistic (∼∼ few
GeV) energies are accelerated near the Sun in at least two ways:(1) by magnetic …

This paper focuses on the interactions between the fast solar wind from coronal holes and
the intervening slower solar wind, leading to the creation of stream interaction regions that …

This is an overview of the solar modulation of cosmic rays in the heliosphere. It is a broad
topic with numerous intriguing aspects so that a research framework has to be chosen to …

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 …

AMS-02 has reached the sensitivity to probe canonical thermal WIMPs by their annihilation
into antiprotons. Due to the high precision of the data, uncertainties in the astrophysical …

Corotating interaction regions are a consequence of spatial variability in the coronal
expansion and solar rotation, which cause solar wind flows of different speeds to become …

An excess of γ rays in the data measured by the Fermi Large Area Telescope in the direction
of the Galactic Center has been reported in several publications. This excess, labeled as the …

The first results are presented from a series of computer simulations of the solar modulation
of galactic cosmic rays using a full three-dimensional model which incorporates all known …

The structure of the heliospheric magnetic field changes substantially during the 11‐year
sunspot cycle. We have calculated its configuration for the period 1976–1982 by using a …

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 …
