Scientific paper

A number of signals involving charged cosmic rays and high-energy photons have been interpreted as being due to annihilating dark matter. This article provides an overview of the experimental evidence and discusses in particular detections of antiprotons and positrons in the cosmic radiation, the diffuse gamma-ray emission between 10 MeV and 100 GeV from the Milky Way, and the 511 keV annihilation radiation and the flux of very high-energy photons (>100 GeV) from the Galactic Centre.
