Abstract

KASCADE and KASCADE-Grande were detector arrays for the measurement of extensive air showers generated by high-energy cosmic rays in the PeV to EeV energy range. KASCADE-Grande has been operated for more than two decades and completed the data taking at the end of 2013. Now, a new analysis of the combined data from the arrays of KASCADE and KASCADE-Grande was performed, increasing both the effective area and the accuracy of the shower reconstruction. In addition, new versions of post-LHC hadronic interaction models are used to interpret the combined data. First results from the new combined analysis confirming earlier observations of spectral features, but also unveiling still existing inconsistencies of the models, will be discussed in this contribution.
