THE RADIO SIGNAL FROM EXTENSIVE AIR SHOWERS

by unknown authors
"... The field of ultra-high energy cosmic rays made a lot of progresses last years with large area experiments such as the Pierre Auger Observatory, HiRes and the Telescope Array. A suppression of the cosmic ray flux at energies above 5.5 × 1019 eV is observed at a very high level of significance but th ..."

V on primary photons and neutrinos and primary cosmic rays are expected to be hadrons. Identifying the precise composition (light or heavy nuclei) will permit to solve the puzzle. It has been proven that the radio signal emitted by the extensive air showers initiated by ultra-high energy cosmic rays reflects

"... Abstract. When Ultra High Energy Cosmic Rays (UHECR) interact with particles in the Earth’s atmosphere, they produce a shower of secondary particles propagating towards the ground. LOPES-30 is an absolute calibrated array of dipole antennas investigating the radio emission from these showers in deta ..."
