Název v původním jazyce

Loss of coherence and change in emission physics for radio emission from very inclined cosmic-ray air showers

Popis výsledku v původním jazyce

Next-generation radio experiments such as the radio detector of the upgraded Pierre Auger Observatory and the planned GRAND and BEACON arrays target the detection of ultra-high-energy particle air showers arriving at low elevation angles. These inclined cosmic-ray air showers develop higher in the atmosphere than vertical ones, enhancing magnetic deflections of electrons and positrons inside the cascade. We evidence two novel features in their radio emission: a new polarization pattern, consistent with a geosynchrotron emission model and a coherence loss of the radio emission, both for showers with zenith angle θ ≳ 65° and strong enough magnetic field amplitude (typical strength of B ∼ 50 μT).
