"2382"^^ . . . . "0"^^ . . "The question of cosmic ray (CR) origin remains the key question of the current astroparticle physics. Direct observations are hampered by the magnetic field deflecting charged particles. One can, however, use very-high-energy (VHE) gamma rays originating in CR interactions as CR tracers. Currently, we participate in the H.E.S.S. experiment detecting VHE cosmic gamma rays. In the proposed project, we intend to focus on analysis and interpretation of the data from this experiment with an emphasis on extended extragalactic objects. We want to finish our preparations for the second phase of the experiment to be finished in 2011. We plan to use the new data to continue with our recently published work that supports the hypothesis of cosmic rays being accelerated at shock fronts in supernova remnants. We also aim to improve the currently used analysis methods in order to further increase the sensitivity. We plan to contribute to the operation of the experimentand to absolve shifts on-site operating the telescopes. We intend to participate in planning of the CTA experiment."@en . .
