Researchers establish fundamental limit on how light bosonic dark matter can be
In a new study published in Physical Review Letters, scientists have estimated a new lower bound on the mass of ultra-lightweight bosonic dark matter particles.
Page 6: Research news on Cosmic rays & astroparticles
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.
