Solving Parker’s transport equation with stochastic differential equations on GPUs
(Elsevier, 2015)
The numerical solution of transport equations for energetic charged particles in space is generally very costly in terms of time. Besides the use of multi-core CPUs and computer clusters in order to decrease the computation ...
Modelling the effects of scattering parameters on particle-drift 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 ...
Time dependence of the e-flux measured by PAMELA during the 2006 July-2009 December solar minimum
(IOP Publishing, 2015)
Precision measurements of the electron component of cosmic radiation provide important information about the
origin and propagation of cosmic rays in the Galaxy not accessible from the study of cosmic-ray nuclear
components ...
The effect of a dynamic inner heliosheath thickness on cosmic-ray modulation
(IOP Publishing, 2015)
The time-dependent modulation of galactic cosmic rays in the heliosphere is studied over different polarity cycles by
computing 2.5 GV proton intensities using a two-dimensional, time-dependent modulationmodel. By ...
Modelling anomalous cosmic ray oxygen in the heliosheath
(EDP Sciences, 2010)
This paper discusses a numerical modulation model to describe anomalous cosmic ray acceleration and transport in the heliosheath, the portion of the heliosphere between the termination shock and the heliopause. The model ...
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 ...
Time dependence of the proton flux measured by Pamela during the 2006 July-2009 December solar minimum
(IOP Science, 2013)
The energy spectra of galactic cosmic rays carry fundamental information regarding their origin and propagation. These spectra, when measured near Earth, are significantly affected by the solar magnetic field. A comprehensive ...
Modeling anomalous cosmic ray oxygen gradients over successive solar cycles
(American Geophysical Union, 2010)
Cosmic ray drift directions depend both on the charge of the particle population under consideration, as well as the heliospheric magnetic field polarity which oscillates within a ∼22 year cycle. The differences in the ...
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 ...
Modeling the modulation of galactic and jovian electrons by stochastic processes
(IOP Publishing, 2011)
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 equations (SDEs) to solve the corresponding ...
