Unveiling the Cosmic Wave: Revolutionizing Our Understanding of Plasma Instability and Cosmic Rays

Scientists have discovered a new plasma instability that generates electromagnetic waves in cosmic rays, challenging previous theories and providing insights into cosmic ray transport in galaxies and their role in galactic evolution. This breakthrough allows for a deeper understanding of the acceleration process and explains why supernova remnants shine in radio and gamma rays. The discovery opens the door to unraveling the fundamental processes of cosmic ray transport in galaxies, which is a major mystery in our understanding of galactic evolution.
