“…Therefore the energy estimator is corrected in order to make it zenith-angle independent. The correction is calculated with the "Constant Intensity Cut" method [14] and used to estimate the signals S 38 for the 1500 m array and S 35 for the denser array that the shower would have produced at the median zenith angles of 38 • and 35 • , respectively.…”

The energy spectrum of high-energy cosmic rays measured with the Pierre Auger Observatory is presented. The measurement is based on data collected until 31 December 2012 and extends over three orders of magnitude in energy from 3 × 10 17 eV up to the very end of the spectrum. The spectral features are presented together with a detailed description of the recent improvements in determination of the energy scale.

“…Now, following the procedure of [11], we selected a subsample of MC data with radial distances, R, between 270 m and 440 m and within an area of 8 × 10 4 m 2 located at the center of the KASCADEGrande array, as they further reduce the systematic bias on N µ . Then, to obtain Λ µ , we applied the constant intensity cut (CIC) method that assumes that the intensity of cosmic rays is isotropic in zenith angle [18]. The method consists of selecting N µ data from different zenith angles by means of cuts applied at fixed frequencies on the integral intensity of N µ for different zenith angle ranges (see fig.…”

Abstract. The KASCADE-Grande observatory was a ground-based air shower array dedicated to study the energy and composition of cosmic rays in the energy interval E = 1 PeV −1 EeV. The experiment consisted of different detector systems which allowed the simultaneous measurement of distinct components of air showers (EAS), such as the muon content. In this contribution, we study the total muon number and the lateral density distribution of muons in EAS detected by KASCADE-Grande as a function of the zenith angle and the total number of charged particles. The attenuation length of the muon content of EAS is also measured. The results are compared with the predictions of the SIBYLL 2.3 high-energy hadronic interaction model.

“…This is especially interesting for cross-checking hadronic interaction models. It makes use of the constant intensity cut (CIC) method that assumes that the intensity of cosmic rays is isotropic in zenith angle, θ [27]. The method consists of selecting EAS data from different zenith angles by means of cuts applied at fixed frequencies.…”

Abstract. The existence of a knee at a few PeV in the all-particle cosmic ray energy spectrum has been well established by several experiments but its physical origin has eluded researches for a long time. It is believed that keys to disentangle the mystery could be found in the spectrum and the composition of cosmic rays between 1 PeV and 1 EeV. A first detailed look into the elemental chemical abundances of cosmic rays in this energy regime was provided by both the KASCADE and the KASCADE-Grande experiments. Their measurements opened the door to a wealth of new data on the subject, which led to the discovery of new structures in the all-particle energy spectrum and the confirmation of knee-like features in the spectra of individual mass groups, as well as the observation of an unexpected ankle-like structure at around 100 PeV in the flux of the light component of cosmic rays. In this contribution, early findings with the KASCADE-Grande experiment will be reviewed and then a short update on the analyses currently performed with the data of the observatory will be presented.
