Description
The last years have been dense with new developments in the search for the sources of Galactic cosmic rays (CRs): 1) The detection of features in the spectra of some primary chemicals opened new questions on the propagation of CRs in the Galaxy. 2) Precise measurements by AMS-02 of secondary nuclei are providing unique information about the transport processes over a larger energy domain 3) HESS, CALET and DAMPE have reported substantial steepening of the total lepton spectrum at ∼TeV with a spectral index softening by about 1. In my talk, I will discuss some of these developments and their implications for our understanding of the origin of cosmic rays.
