{wiki=Category:Cosmic_ray_physicists}
Cosmic ray physicists are scientists who study cosmic rays, which are high-energy particles originating from outer space that travel through the Earth's atmosphere and can reach the surface. These particles mainly consist of protons, atomic nuclei, and, to a lesser extent, electrons and positrons. Cosmic rays can originate from various astrophysical phenomena, including supernovae, active galactic nuclei, and other high-energy astrophysical events.
