The chargesign dependent effect in the solar modulation of cosmic rays
(Elsevier, 2014)The centennial anniversary of the discovery of cosmic rays was in 2012. Since this discovery considerable progress has been made on several aspects related to galactic cosmic rays in the heliosphere. It is known that they ... 
Cosmic rays in the inner heliosphere: insights from observations, theory and models
(Springer, 2011)The global modulation of galactic cosmic rays in the inner heliosphere is determined by four major mechanisms: convection, diffusion, particle drifts (gradient, curvature and current sheet drifts), and adiabatic energy ... 
A local interstellar spectrum for galactic electrons
(ELSEVIER, 2013)A heliopause spectrum at 122 AU from the Sun is presented for galactic electrons over an energy range from 1 MeV to 50 GeV that can be considered the lowest possible local interstellar spectrum (LIS). The focus of this ... 
Modelling and observing Jovian electron propagation times in the inner heliosphere
(ELSEVIER, 2013)The propagation of Jovian electrons in interplanetary space was modelled by solving the relevant transport equation numerically through the use of stochastic differential equations. This approach allows us to calculate, ... 
Modelling of lowenergy galactic electrons in the heliosheath
(Elsevier, 2011) 
Modelling the effects of scattering parameters on particledrift in the solar modulation of galactic cosmic rays
(Elsevier, 2015)It is well known that particle drift motions are suppressed by diffusive scattering as established by direct numerical simulations. The effect of constant scattering on the drift velocities of charged particles has always ... 
Modulation of galactic cosmic rays in a northsouth asymmetrical heliosphere
(Elsevier, 2011) 
New insights from modeling the neutral heliospheric current sheet
(Springer, 2015)Recently, the modulation of cosmic rays in the heliosphere has increasingly been studied by solving the well known transport equation via an approach based on stochastic differential equations. This approach, which is ... 
On the propagation times and energy losses of cosmic rays in the heliosphere
(American Geophysical Union, 2011)We present calculations of the propagation times and energy losses of cosmic rays as they are transported through the heliosphere. By calculating these quantities for a spatially 1D scenario, we benchmark our numerical ...
