Origin of cosmic rays: still a mystery — •Felix Aharonian — DIAS, 31 Fitzwilliam Place, Dublin 2, Ireland — MPIK, Saupfercheckweg 1, 69117 Heidelberg, Germany

Despite the remarkable achievements in cosmic ray studies via direct measurements of charge relativistic particles, as well as through the probes of cosmic ray densities in different astrophysical environments using high and very high energy gamma-rays, the origin of cosmic rays remains highly uncertain. This concerns both the galactic and extragalactic components of cosmic rays. I will briefly highlight the status of the field, critically review the current models, and discuss the possible breakthroughs in the field expected in the context of future major space and ground-based projects.
