Three types of extreme-energy space particles may have unified origin

Three types of extreme-energy space particles may have unified origin 01/24/2018 12:33 PM EST One of the biggest mysteries in astroparticle physics has been the origins of ultrahigh-energy cosmic rays, very high-energy neutrinos, and high-energy gamma rays. Now, a new theoretical model reveals that they all could be shot out into space after cosmic rays are accelerated by powerful jets from supermassive black holes. The model may set a new milestone on the path toward solving the half-century-old enigma of the origin of the highest-energy particles in the universe.
