Description
The Radio Detector (RD) at the Pierre Auger Observatory is a new large-scale instrument designed to measure the highest-energy cosmic rays. It consists of 1660 radio antennas spread across 3000 km², detecting the radio emission from extensive air showers in the 30–80 MHz range. By combining these measurements with data from water-Cherenkov detectors, we can determine both the energy and composition of cosmic rays at extreme energies. The full detector was completed in late 2024 and is now operational. First results show a strong correlation between radio-based energy measurements and traditional detection methods, confirming the precision of the system. We highlight an extraordinary 36 EeV air shower with a radio signal stretching over 50 km, demonstrating the unique power of radio detection for studying the most energetic particles in the universe.
