TL;DR: In this paper, a composition analysis of KASCADE air shower data is performed by means of unfolding the two-dimensional frequency spectrum of electron and muon numbers, and the analysis is the determination of energy spectra for elemental groups representing the chemical composition of primary cosmic rays.

TL;DR: The results show that it should be possible to determine the nature and composition of UHECRs with combined radio and particle detectors, and to detect the ultrahigh-energy neutrinos expected from flavour mixing.

TL;DR: In this article, the results of an analysis of the large-scale anisotropy of cosmic rays in the PeV range were presented, and the Rayleigh formalism was applied to the right ascension distribution of extensive air showers measured by the KASCADE (Karlsruhe Shower Core and Array Detector) experiment.

TL;DR: In this article, the authors examined the contribution of an electric field to the radio emission mechanism theoretically and experimentally, and found that during thunderstorms, radio emission can be strongly enhanced.
