Recent Results from the KASCADE-Grande Data Analysis — •Donghwa Kang for the KASCADE-Grande-Collaboration — Karlsruher Institut für Technologie, Karlsruhe, Germany

KASCADE and its extension KASCADE-Grande finished data taking in 2013 to measure individual air showers of cosmic rays with energies from 100 TeV up to 1 EeV. The experiment was completely dismantled in 2013 though, the data analysis is still in progress. Recently, we investigated the validity of the new hadronic interaction model SIBYLL 2.3c. We also published a new result of a search for large-scale anisotropies performed with the KASCADE-Grande data. Investigation of the attenuation length of the muon content of very-high energy air showers in the atmosphere is also updated with the predictions of the SIBYLL 2.3 interaction model. We investigated, in addition, the muon content of EAS and compared them to all post-LHC interaction models. In this contribution, these recent results from KASCADE-Grande will be discussed. An update of the internet-based data center of KCDC offering the original scientific data from KASCADE-Grande to the public will be briefly discussed as well.
