#### 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 ...

#### Possible evidence for a fisk-type heliospheric magnetic field, 1: analyzing Ulysses/Ket electron observations

(IOP Publishing, 2011)

The propagation of energetic charged particles in the heliospheric magnetic field is one of the fundamental problems in heliophysics. In particular, the structure of the heliospheric magnetic field remains an unsolved ...

#### Time-dependent modulation of cosmic rays in the heliosphere

(Springer Verlag, 2014)

The time-dependent modulation of galactic cosmic rays in the heliosphere is studied
by computing intensities using a time-dependent modulation model. By introducing recent
theoretical advances in the transport coefficients ...

#### A stochastic approach to galactic proton propagation: influence of the spiral arm structure

(Elsevier, 2014)

A newly developed numerical code solving Fokker–Planck type transport equations in currently four
dimensions (space plus momentum or energy) and time by means of stochastic differential equations
(SDEs) is applied to the ...

#### Cosmic-ray modulation: an ab initio approach

(Springer Verlag, 2014)

A better understanding of cosmic-ray modulation
in the heliosphere can only be gained through a proper understanding
of the effects of turbulence on the diffusion and drift
of cosmic rays. We present an ab initio model ...

#### An AB initio model for the modulation of galactic cosmic-ray electrons

(IOP Science, 2013)

The modulation of galactic cosmic-ray electrons is studied using an ab initio three-dimensional steady state cosmicraymodulation
code in which the effects of turbulence on both the diffusion and drift of these cosmic-rays ...

#### Modeling drift along the heliospheric wavy neutral sheet

(IOP Publishing, 2012)

Drift along the wavy heliospheric neutral sheet is believed to play an important role in cosmic-ray modulation and can explain the peaked versus flat intensity profiles during consecutive solar magnetic epochs. Modulation ...

#### An AB initio model for cosmic-ray modulation

(IOP Science, 2013)

A proper understanding of the effects of turbulence on the diffusion and drift of cosmic rays (CRs) is of vital
importance for a better understanding of CR modulation in the heliosphere. This study presents an ab initio ...

#### Sensitivity of cosmic-ray proton spectra to the low-wavenumber behavior of the 2D turbulence power spectrum

(American Astronomical Society, 2015)

In this study, a novel ab initio cosmic ray (CR) modulation code that solves a set of stochastic transport equations
equivalent to the Parker transport equation, and that uses output from a turbulence transport code as ...

#### On aspects pertaining to the perpendicular diffusion of solar energetic particles

(American Astronomical Society, 2015)

The multitude of recent multi-point spacecraft observations of solar energetic particle (SEP) events has made it
possible to study the longitudinal distribution of SEPs in great detail. SEPs, even those accelerated during ...
