New Explaination for Cosmic Rays - Universe Today
Scientists at the Los Alamos National Laboratory have come up with a new theory to help explain how giant radio galaxies could create cosmic rays; through a process called magnetic field reconnection. According to this theory, the magnetic field lines of the supermassive black holes at the heart of these galaxies connect and vanish, converting the energy of the field into a spray of particles. Cosmic rays are a mystery to astronomers because they have so much energy, there doesn't seem to be anything in the Universe that could propel them.
