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: In this article, a method is developed to search for air showers initiated by photons using data recorded by the surface detector of the Auger Observatory, based on observables sensitive to the longitudinal shower development, the signal risetime and the curvature of the shower front.
