On modelling the 2017 galactic cosmic ray depression
O. P. M. Aslam, D. MacTaggart, M. S. Potgieter +2
In the second half of 2017, as Solar Cycle 24 approached its minimum, a pronounced and rigidity-dependent depression in the galactic cosmic ray (GCR) proton flux was observed using…
The source of the 2017 cosmic ray half-year modulation event
O. P. M. Aslam, D. MacTaggart, R. Battiston +2
In 2017, as the solar cycle approached solar minimum, an unusually long and large depression was observed in galactic cosmic ray (GCR) protons, detected with the Alpha Magnetic Spe…
Modulation of cosmic ray anti-protons in the heliosphere: simulations for a solar cycle
O. P. M. Aslam, M. S. Potgieter, Xi Luo +1
The precision measurements of galactic cosmic ray protons from PAMELA and AMS are reproduced using a well-established 3D numerical model for the period July 2006 - November 2019. T…
Unfolding Drift Effects for Cosmic Rays over the Period of the Sun's Magnetic Field Reversal
O. P. M. Aslam, Xi Luo, M. S. Potgieter +2
A well-established, comprehensive 3-D numerical modulation model is applied to simulate galactic protons, electrons and positrons from May 2011 to May 2015, including the solar mag…
Helium fluxes measured by the PAMELA experiment from the minimum to the maximum solar activity for solar cycle 24
N. Marcelli, M. Boezio, A. Lenni +53
Time-dependent energy spectra of galactic cosmic rays (GCRs) carry fundamental information regarding their origin and propagation. When observed at the Earth, these spectra are sig…
Acceleration of galactic electrons at the solar wind termination shock and Voyager 1 observations
M. S. Potgieter, P. L. Prinsloo, R. D. Strauss
Diffusive shock acceleration (DSA), as an acceleration process for Galactic electrons at the solar wind termination shock (TS), is investigated with a comprehensive numerical model…
Time dependence of the electron and positron components of the cosmic radiation measured by the PAMELA experiment between July 2006 and December 2015
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +52
Cosmic-ray electrons and positrons are a unique probe of the propagation of cosmic rays as well as of the nature and distribution of particle sources in our Galaxy. Recent measurem…
