Outline of Final Research Achievements

Our aim is to find the origin of cosmic ray protons. We observed TeV unidentified sources with X-ray satellite Suzaku, and found that around half of them are pulsar wind nebulae. On the other hand, it is still unclear that what is the main accelerator of cosmic ray proton. We also made detailed study of the accelerator candidate, shocks of supernova remnants, and discussed on the acceleration efficiency. We also found the escaping particles from the shocks of supernova remnants for the first time.
