Is the highest cosmic-ray flux yet to come?
(Springer, 2014)
The recent 2009 solar-minimum period was characterized by a record-setting high
Galactic cosmic-ray flux observed at Earth. This, along with the unexpected low heliospheric
magnetic-field magnitude, caused this period ...
Implications of Voyager 1 observations beyond the heliopause for the local interstellar electron spectrum
(IOP Publishing, 2014)
Cosmic-ray observations made by the Voyager 1 spacecraft outside the dominant modulating influence of the heliosphere finally allow the comparison of computed galactic spectra with experimental data at lower energies. These ...
A study of the global heliospheric modulation of galactic carbon
(Elsevier, 2014)
Observations of galactic Carbon in the heliosphere provide a useful tool with which a comprehensive description of the global
modulation of cosmic rays both inside and outside off the solar wind termination shock (TS) can ...
The charge-sign 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 ...
Where does the heliospheric modulation of galactic cosmic rays start?
(Elsevier, 2014)
The long outstanding question of where the heliospheric (solar) modulation of galactic cosmic rays actually begins, in terms of spatial
position, as well as at what high kinetic energy, can now be answered. Both answers ...
Cosmic rays in the heliosphere: observations
(Elsevier, 2014)
This contribution to the 100th commemoration of the discovery of cosmic rays (6–8 August, 2012 in Bad Saarow, Germany) is about observations of those cosmic rays that are sensitive to the structure and the dynamics of the ...
Discovery of the hard spectrum VHE γ-ray source HESS J1641-463
(IOP Publishing, 2014)
This Letter reports the discovery of a remarkably hard spectrum source, HESS J1641–463, by the High Energy Stereoscopic System (H.E.S.S.) in the very high energy (VHE) domain. HESS J1641–463 remained unnoticed by the usual ...
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. ...
Time-dependent modulation of cosmic rays in the heliosphere
(Springer, 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 ...
