In the last fifteen years radio detection made it back to the list of promising techniques for
extensive air showers, firstly, due to the installation and successful operation of digital radio …

In 1965 it was discovered that cosmic ray air showers emit impulsive radio signals at
frequencies below 100 MHz. After a period of intense research in the 1960s and 1970s …

The observation of electromagnetic radiation from radio to γ-ray wavelengths has provided a
wealth of information about the Universe. However, at PeV (10 15 eV) energies and above …

This article presents the design of the Radio Neutrino Observatory Greenland (RNO-G) and
discusses its scientific prospects. Using an array of radio sensors, RNO-G seeks to measure …

Abstract The Pierre Auger Observatory, located on a vast, high plain in western Argentina, is
the world׳ s largest cosmic ray observatory. The objectives of the Observatory are to probe …

A bstract Neutrino interactions with protons and neutrons probe their deep structure and may
reveal new physics. The higher the neutrino energy, the sharper the probe. So far, the …

The Pierre Auger Observatory has begun a major Upgrade of its already impressive
capabilities, with an emphasis on improved mass composition determination using the …

The mass composition of cosmic rays contains important clues about their origin. Accurate
measurements are needed to resolve longstanding issues such as the transition from …

The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is
used to detect the radio emission of cosmic-ray air showers. These observations are …
