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.
A century after their discovery, cosmic rays—particles of extreme energy originating from the far reaches of the universe—remain a mystery to scientists. The DAMPE (Dark Matter Particle Explorer) space telescope is tackling ...

A detector buried deep in Antarctic ice has captured the first experimental evidence of a predicted but never-before-seen phenomenon: radio pulses generated when high-energy cosmic rays slam into the ice sheet and trigger ...
In the exotic world of particle physics, neutrinos may be the most mysterious members. They rarely interact with other matter, have almost no mass, and have no electrical charge. These characteristics make them extremely ...
