Probing the Origin of Cosmic Rays with High Energy Gamma Rays
Prof. Felix Aharonian (Dublin)

Gamma-rays carry crucial information about the most energetic and violent phenomena in the Universe. The respective research field, the gamma-ray astronomy, is a part of the modern interdisciplinary area called astroparticle physics. It addresses an impressive range of topics related to nonthermal processes in a large variety of astrophysical environments: from compact relativistic objects like pulsars and accreting black-holes to large-scale cosmological structures like clusters of galaxies. In my talk, I will discuss the role of very high energy gamma-ray astronomy for the solution of one of the central problems of astroparticle physics - the Origin of Cosmic Rays.
