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.
When an invisible entity making up 85% of the universe's mass stumps the greatest scientific minds of our time, awe is an understandable response.

Dark matter, a type of matter that does not emit, reflect or absorb light, is predicted to account for most of the matter in the universe. As it eludes common experimental techniques for studying ordinary matter, understanding ...
Neutrinos are extremely lightweight and electrically neutral particles that rarely interact with ordinary matter. Due to these rare interactions, neutrinos can travel across space almost entirely unaffected, carrying information ...
Imagine looking up at the night sky and seeing a star suddenly burst into a blaze of light brighter than anything nearby. A flash so bright that it briefly outshines an entire galaxy before fading forever.

The KM3NeT collaboration is a large research group involved in the operation of a neutrino telescope network in the deep Mediterranean Sea, with the aim of detecting high-energy neutrino events. These are rare and fleeting ...
Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields remain poorly understood. ...
Hypothetical dark matter stars known as "boson stars" could leave telltale ripples across the cosmos, offering researchers a new way to probe the invisible forces shaping the universe. In 2019, a strange event was observed ...

Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to detect using conventional experimental techniques, as it does not emit, absorb, or reflect light. ...
Ciaran O'Hare scribbles symbols using colored markers across his whiteboard like he's trying to solve a crime—or perhaps planning one. He bounces around the edges of the board, slowly filling it with sharp angles and curling ...
