Cosmic ray electrons and positrons are currently measured with unprecedented precision up to TeV energies, and represent an unique probe for the local properties of our Galaxy. The interpretation of the fluxes observed at Earth is at present still debated, especially for the excess of positrons above 10 GeV measured by Pamela, Fermi-LAT and AMS-02 experiments, which suggests the presence of a local, primary source of cosmic positrons.
We will discuss recent strategies and results aimed at constraining the properties of cosmic-ray electron and positron accelerators, based on their multi-messenger and multi-wavelength emission.
