Description
With the deployment of new experiments for the detection of high-energy particles in space, a new era in cosmic-ray physics has started. Thanks to space missions such as PAMELA, AMS-02, CALET, DAMPE and ISS-CREAM, the recent years are marked with many breakthroughs in this field; unexpected observations have challenged the accuracy of established models, and other discoveries are expected to come in the near future.
In this seminar, I will review the state-of-the-art on our knowledge and ignorance of the astrophysics of cosmic rays, from their sources to their transport in the interplanetary space.
I will present the recent theoretical developments and how they compare with the new observations on primary nuclei, secondary to primary ratios, and antimatter nuclei. I will focus on some critical problems in cosmic-ray propagation models, their possible solutions in light of the recent data, and the implications for future research in this field.
