Cosmic Rays & Particle Acceleration: Physical Mechanisms

Cosmic rays are high-energy charged particles, mostly atomic nuclei, arriving at Earth from the Sun, Galactic sources, and at the highest energies likely extragalactic accelerators. Cosmic-ray studies connect plasma physics, supernova feedback, interstellar chemistry, neutrino astronomy, and extreme particle acceleration.
