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.
In a landmark discovery that bridges nearly a century of theoretical physics, a Chinese research team has successfully captured the first direct evidence of the Migdal effect, a breakthrough with profound implications for ...

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is estimated to account for most of the universe's mass. Over the past decades, many physicists worldwide have been trying to detect ...
Using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), astronomers from the Chinese Academy of Sciences (CAS) and elsewhere have observed a nearby pulsar known as PSR J2129+4119. Results of the observational ...
Does dark matter follow the same laws as ordinary matter? The mystery of this invisible and hypothetical component of our universe—which neither emits nor reflects light—remains unsolved. A team involving members from ...
