Cosmic Rays Propagating Through Milky Way Interact with Matter Producing Excess Antimatter Counterpart of Electron
Researchers from the Raman Research Institute (RRI), Bengaluru, an autonomous institution of the Department of Science and Technology have resolved the mystery in a new study published in the Journal of High Energy Astrophysics. Their proposal is simple –– cosmic rays while propagating through the Milky Way galaxy interact with matter producing other cosmic rays, primarily electrons and positrons. The authors Agnibha De Sarkar, Sayan Biswas and Nayantara Gupta argue that these new cosmic rays are the origin of the ‘positron excess’ phenomenon.
