Particle astrophysics

Particle astrophysics is the study of fundamental particles travelling through space, particularly those that reach the Earth. These cosmic rays include photons, protons, alpha particles and neutrinos. Some of these decay to other particles in the atmosphere, while neutrinos can pass through the entire Earth without being absorbed.
