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.
Determining the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles in physics. New results from the world's most sensitive dark matter detector, LUX-ZEPLIN ...

A recent Physical Review Letters publication presents a thorough analysis of MicroBooNE detector data, investigating the anomalous surplus of neutrino-like events detected by the preceding MiniBooNE experiment.
About 80% of the universe's mass is thought to consist of dark matter. Yet, little is known about the composition and structure of the particles that make up dark matter, presenting physicists with some fundamental questions. ...

Dark matter (DM) is a type of matter estimated to account for 80% of the universe's total mass, but it cannot be directly detected using conventional experimental techniques. As DM does not emit, reflect or absorb light, ...
A new study from NYU Abu Dhabi has found that high-energy particles from space, known as cosmic rays, could create the energy needed to support life underground on planets and moons in our solar system.
