AbstractIt has been one of the biggest problems what is the origin of Galactic cosmic-rays. Previous X-ray surveys found several supernova remnants (SNRs) which have synchrotron X-rays, although the number is too small to account for the total energy of cosmic-rays. HESS, on the other hand, discovered tens of new unidentified (TeV unID) sources on the Galactic plane, which could be the main contributors of the Galactic cosmic-rays. However, we need follow-up observations to understand the nature of these TeV unID sources. Suzaku has already done deep follow-up observations of most TeV unIDs and pin-pointed their nature. Only one TeV inID source is categorized as an SNR, whereas several sources are identified as pulsar wind nebulae (PWNe). In this paper, we will discuss on what is the main contributors of TeV unID sources and Galactic cosmic-rays. We also discuss on GeV observations of TeV unIDs and future aspects.
