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…

Solar energetic particle events observed by the PAMELA mission

A. Bruno, G. A. Bazilevskaya, M. Boezio +55

Despite the significant progress achieved in recent years, the physical mechanisms underlying the origin of solar energetic particles (SEPs) are still a matter of debate. The compl…
