Observation of inclined EeV air showers with the radio detector of the Pierre Auger Observatory

Extensive air showers, initiated in the Earth’s atmosphere by high-energy cosmic rays, emit pulsed radio signals with a typical duration of tens of nanoseconds. With the Auger Engineering Radio Array (AERA), consisting of 150 detector stations on an area of 17 km2, we measure these signals in the 30 to 80 MHz band. For air showers arriving within 60° from the vertical, the radio emission illuminates only limited areas on the ground, of order a few hundred meters in diameter. Consequently, radio signals are typically detectable only in a handful of AERA radio detector stations for a given air shower.
