Seminario dr.ssa Martina Cardillo Cosmic-­‐Rays are very high energy particles, mainly rotons, that from their sources to Earth with a power-­law spectral distribution, energy of about 10^20 eV. Despite the great amount of data collected from their discovery (in 1912), we are not yet able to understand one of the most important issue: what is CR's origin Where are they accelerated? The best candidate as sources for the part of CR's spectrum up to energy of about 10^15 eV) are Supernova Remnants but there is the lack of a direct of CR's acceleration in theirshocks. Our work is focused on this topic. Our aim is a better understanding of the connectionbetween SNR and Galactic CRs through the development of realistic models that can explain experimental data from gamma-ray satellites and particle detectors. So far, the only thing that can be considered as certain is that, for the high-­energy astrophysics, “this is a tricky situation”
