Understanding variations of galactic energetic particles in the heliosphere: modelling and radiation hazard assessment
Miguel Orcinha, Fernando Barão, Bruna Bertucci +3
The intensity and energy spectrum of energetic charged radiation in the heliosphere are significantly influenced by solar activity. This phenomenon is known as solar modulation of…
Numerical modeling of cosmic-ray transport in the heliosphere and interpretation of the proton-to-helium ratio in Solar Cycle 24
Nicola Tomassetti, Fernando Barão, Bruna Bertucci +2
Thanks to space-borne experiments of cosmic-ray (CR) detection, such as the AMS and PAMELA missions in low-Earth orbit, or the Voyager-1 spacecraft in the interstellar space, a lar…
Observation of a time lag in solar modulation of cosmic rays in the heliosphere
Miguel Orcinha, Nicola Tomassetti, Fernando Barão +1
The solar modulation effect of Galactic cosmic rays is a time-dependent phenomenon that is caused by the transport of these particles through the magnetized plasma of the heliosphe…
Evidence for a Time Lag in Solar Modulation of Galactic Cosmic Rays
Nicola Tomassetti, Miguel Orcinha, Fernando Barao +1
The solar modulation effect of cosmic rays in the heliosphere is an energy-, time-, and particle-dependent phenomenon which arises from a combination of basic particle transport pr…
Precision measurement of the (e + e) flux in primary cosmic rays from 0.5 GeV to 1 TeV with the Alpha Magnetic Spectrometer on the International Space Station
Manuela Vecchi
We present a precise measurement of the combined electron plus positron flux from 0.5 GeV to 1 TeV, based on the analysis of the data collected by the Alpha Magnetic Spectrometer d…
Precision Measurement of the Proton Flux in Primary Cosmic Rays from 1 GV to 1.8 TV with the Alpha Magnetic Spectrometer on the International Space Station
Cristina Consolandi
A precision measurement of the proton flux in primary cosmic rays with rigidity from 1 GV to 1.8 TV is presented based on 300 million events. The results show that the proton flux…
