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.
Scientists search for "decaying" dark matter (DDM) because it offers unique signatures like specific X-ray or gamma-ray lines or neutrino signals not seen in normal matter, potentially revealing dark matter's particle nature, ...

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 the ...

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is predicted to account for most of the universe's mass. As it cannot be detected and studied using conventional experimental techniques, ...
Neutrinos are one of the most enigmatic particles in the standard model. The main reason is that they're so hard to detect. Despite the fact that 400 trillion of them created in the sun are passing through a person's body ...

Over the past decades, many research teams worldwide have been trying to detect dark matter, an elusive type of matter that does not emit, reflect or absorb light, using a variety of highly sensitive detectors. Ultimately, ...
Researchers hope to use neutrinos to find the sources of cosmic radiation. New algorithms out of Bochum are aiding in the search, and have also eliminated a few candidates.
