Fast, relativistic particles (protons, electrons, nuclei, gamma rays, ...) coming from space.
Athens Neutron Monitor
Observing cosmic ray neutrons. Background information, explanation of worldwide monitor network, detector description, publications, links.
Cosmic Ray Puzzle Solved
Increased estimates of extragalactic magnetic fields may explain why possible HE CR sources, like AGN M87, do not align with observed CR directions.
High Resolution Fly's Eye Experiment (HiRes)
Large air fluorescence cosmic ray detector.
Institute for Cosmic Ray Research, University of Tokyo.
Nuclei Cooperate to Produce Single Particle
Ultrahigh energy photons striking matter can transform into rho mesons through an interaction that involves many nuclei simultaneously, a phenomenon that may affect the detection signatures of high-energy particles from space.
Pierre Auger Cosmic Ray Observatory
Aims to observe the highest-energy cosmic rays.
Solar Tower Atmospheric Cherenkov Effect Experiment.
