Cosmic rays & astroparticles is a research area focused on high-energy particles of extraterrestrial origin and their role in fundamental physics and astrophysics. It encompasses experimental and theoretical studies of primary cosmic rays (protons, nuclei, electrons), secondary air-shower particles, gamma rays, neutrinos, and other non-photonic messengers that probe extreme environments such as supernova remnants, active galactic nuclei, and compact objects. The field integrates particle detection techniques, high-energy astrophysics, plasma and magnetic field modeling, and multi-messenger observations to investigate particle acceleration mechanisms, propagation in interstellar and intergalactic media, and potential signatures of new physics beyond the Standard Model.
For nearly a century, scientists around the world have been searching for dark matter—an invisible substance believed to make up about 80% of the universe's mass and needed to explain a variety of physical phenomena. Numerous ...
