The creation of synthetic digital ground-truth images of historic cosmic ray data recordings
(Springer, 2017)
The aim of this paper is to develop a set of algorithms for the automated construction of synthetic digital ground truth images from historic cosmic ray recordings. These images can subsequently be used to test data ...
A numerical study of Forbush decreases with a 3D cosmic-ray modulation model based on an SDE approach
(IOP Publishing, 2017)
Based on the reduced diffusion mechanism for producing Forbush decreases (Fds) in the heliosphere, we constructed a three-dimensional (3D) diffusion barrier, and by incorporating it into a stochastic differential equation ...
Prospects for Cherenkov Telescope Array observations of the young supernova remnant RX J1713.7−3946
(AAS, 2017)
We perform simulations for future Cherenkov Telescope Array (CTA) observations of RX J1713.7−3946, a young supernova remnant (SNR) and one of the brightest sources ever discovered in very high energy (VHE) gamma rays. ...
Heliosheath processes and the structure of the heliopause: modeling energetic particles, cosmic rays, and magnetic fields
(Springer, 2017)
This paper summarizes the results obtained by the team “Heliosheath Processes and the Structure of the Heliopause: Modeling Energetic Particles, Cosmic Rays, and Magnetic Fields” supported by the International Space Science ...
A hitch-hiker’s guide to stochastic differential equations: solution methods for energetic particle transport in space physics and astrophysics
(Springer, 2017)
In this review, an overview of the recent history of stochastic differential equations (SDEs) in application to particle transport problems in space physics and astrophysics is given. The aim is to present a helpful working ...
Toward a greater understanding of the reduction of drift coefficients in the presence of turbulence
(IOP Publishing, 2017)
Drift effects play a significant role in the transport of charged particles in the heliosphere. A turbulent magnetic field is also known to reduce the effects of particle drifts. The exact nature of this reduction, however, ...
The re-acceleration of galactic electrons at the heliospheric termination shock
(IOP Publishing, 2017)
Observations by the Voyager spacecraft in the outer heliosphere presented several challenges for the paradigm of diffusive shock acceleration (DSA) at the solar wind termination shock (TS). In this study, the viability of ...
On the effects of pickup ion-driven waves on the diffusion tensor of low-energy electrons in the heliosphere
(IOP Publishing, 2017)
The effects of Alfvén cyclotron waves generated due to the formation in the outer heliosphere of pickup ions on the transport coefficients of low-energy electrons is investigated here. To this end, parallel mean free path ...
Perpendicular diffusion of solar energetic particles: model results and implications for electrons
(IOP Publishing, 2017)
The processes responsible for the effective longitudinal transport of solar energetic particles (SEPs) are still not completely understood. We address this issue by simulating SEP electron propagation using a spatially 2D ...
New evidence for charge-sign-dependent modulation during the solar minimum of 2006 to 2009
(IOP Publishing, 2017)
The PAMELA space experiment, in orbit since 2006, has measured cosmic rays (CRs) through the most recent period of minimum solar activity with the magnetic field polarity as A < 0. During this entire time, galactic electrons ...
