Cosmic-ray modulation equations
(Springer, 2011)
The temporal variation of the cosmic-ray intensity in the heliosphere is called cosmic-ray modulation. The main periodicity is the response to the 11-year solar activity cycle. Other variations include a 27-day solar ...
Cosmic ray modulation in the outer heliosphere: predictions for cosmic ray intensities up to the heliopause along Voyager 1 and 2 trajectories
(Elsevier, 2011)
Time dependent cosmic ray modulation in the outer heliosphere is calculated and results are compared to Voyager 1 and 2 observations using a two-dimensional time-dependent cosmic ray transport model. We predict possible ...
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 ...
Primary particle acceleration above 100 TeV in the shell-type supernova remnant RX J1713.7-3946 with deep H.E.S.S. observations (Corrigendum to article: Primary particle acceleration above 100 TeV in the shell-type supernova remnant RX J1713.7-3946 with deep HESS observations, 464(1):235-243.)

Primary particle acceleration above 100 TeV in the shell-type supernova remnant RX J1713.7-3946 with deep H.E.S.S. observations (Corrigendum)
Galactic cosmic rays in the outer heliosphere: theory and models
(Springer, 2011)
We review recent advances in the field of galactic cosmic ray transport in the distant heliosphere. The advent of globalMHD models brought about a better understanding of the three-dimensional structure of the interface ...
Modulation of galactic protons in the heliosphere during the unusual solar minimum of 2006 to 2009
(Springer Verlag, 2014)
The last solar minimum activity period, and the consequent minimum modulation
conditions for cosmic rays, was unusual. The highest levels of galactic protons were
recorded at Earth in late 2009 in contrast to expectations. ...
The contribution of millisecond pulsars to the Galactic cosmic-ray lepton spectrum
(Elsevier, 2015)
Pulsars are believed to be sources of relativistic electrons and positrons. The abundance of detections of γγ-ray millisecond pulsars by Fermi Large Area Telescope coupled with their light curve characteristics that imply ...
A Fisk-Parker hybrid heliospheric magnetic field with a solar-cycle dependence
(IOP Publishing, 2008)
We present a refinement of the Fisk-Parker hybrid field of Burger and Hitge which now includes a region bordering the solar rotational equator where magnetic field footpoint motion occurs only through diffusive reconnection. ...
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 ...
Modeling ground and space based cosmic ray observations
(Elsevier, 2012)
After entering our local astrosphere (called the heliosphere), galactic cosmic rays, as charged particles, are affected by the Sun’s turbulent magnetic field. This causes their intensities to decrease towards the inner ...
