Particle astrophysics is a research area at the interface of particle physics, astrophysics, and cosmology that investigates fundamental particles and their interactions using astrophysical sources and environments. It focuses on high-energy messengers such as cosmic rays, gamma rays, neutrinos, and, increasingly, gravitational waves to probe processes in extreme settings like supernovae, active galactic nuclei, compact object mergers, and the early universe. The field seeks to constrain particle properties, test physics beyond the Standard Model, study dark matter and dark energy candidates, and elucidate acceleration and propagation mechanisms through multi-messenger observations and advanced detection techniques.
