In this paper we review air shower data related to the mass composition of cosmic rays
above 1015eV. After explaining the basic relations between air shower observables and the …

This review summarizes recent developments in the understanding of high-energy cosmic
rays. It focuses on galactic and presumably extragalactic particles in the energy range from …

A composition analysis of KASCADE air shower data is performed by means of unfolding the
two-dimensional frequency spectrum of electron and muon numbers. Aim of the analysis is …

KASCADE has been designed to measure air showers of primary cosmic-ray energies in the
PeV region and to investigate the knee phenomenon in the all-particle energy spectrum …

We discuss the possibilities of measuring ultra-high energy cosmic rays and neutrinos with
radio techniques. We review a few of the properties of radio emission from cosmic ray air …

We present a complete phenomenological model accounting for the evolution of the cosmic
ray spectrum and composition with energy, based on the available data over the entire …

Cosmic ray air showers have been known for over 30 years to emit pulsed radio emission in
the frequency range from a few to a few hundred MHz, an effect that offers great …

KASCADE and KASCADE-Grande were multi-detector installations to measure individual air
showers of cosmic rays at ultra-high energy. Based on data sets measured by KASCADE …

Certain aspects of ultra-high energy (UHE) cosmic ray astrophysics require correlated
studies on the electron and muon components of air showers, namely, the search for cosmic …

Neutrino astrophysics offers new perspectives on the Universe investigation: high-energy
neutrinos, produced by the most energetic phenomena in our Galaxy and in the Universe …
