New Results from the KASCADE-Grande Data Analysis — •Donghwa Kang for the KASCADE-Grande collaboration — Karlsruhe Institute of Technology, Karlsruhe

KASCADE-Grande and its original array of KASCADE measured individual air showers of cosmic rays in the energy range of 100 TeV up to 1 EeV. The data accumulation was fully completed at the end of 2013 though, the data analysis is still in progress. Recently, we published two new results: The estimation on upper limits to the flux of ultra-high energy gamma rays, which set constraints on some fundamental astrophysical models. And the determination of the muon attenuation length by investigations on the evolution of the muon content of very-high energy air showers in the atmosphere, compared to the predictions of various hadronic interaction models.

In addition, we updated KCDC, the web-based platform where we publish the data from KASCADE and KASCADE-Grande with more than 20 years measurements. A new version of the KASCADE Cosmic Ray Data Centre (KCDC) is released, named NABOO 2.0, where we now also provide air-shower simulation data sets for three different hadronic interaction models.

In this contribution, recent results from KASCADE-Grande and the update of KCDC will be briefly discussed.
