Towards joint analysis of KASCADE and Tunka-133 data — •Victoria Tokareva1, Andreas Haungs1, and Dmitriy Kostunin21Institute for Nuclear Physics, Karlsruhe Institute of Technology, DE-76021, Karlsruhe, Germany — 2Deutsches Elektronen-Synchrotron, DE-15738, Zeuthen, Germany

Ultra-high-energy cosmic rays (1014 − 1018 eV) that are produced in extreme astrophysical processes can provide us with possible hints about the physical nature of these processes. In particular, one could be highly interested in studying neutral particles like primary gamma rays, which are not deflected by galactic magnetic fields and thus can be associated with the particular source that produced them.

The flux of ultra-high-energy gamma events registered by modern experiments (HAWC, Tibet, Carpet-2, etc.) is quite low, so the challenge of increasing the statistics of the events in question, as well as multicomponent air-showers investigation, are highly relevant.

The talk is going to consider a possible joint analysis of data from two observatories, KASCADE (Germany) and Tunka-133 (Russia). The data mapping for two observatories is going to be discussed as well as the current status of the data processing.
