Description

PeVatrons are astrophysical sources which are supposed to accelerate charged
particles up to PeV energies. Studying PeVatrons would help us to understand acceleration processes of cosmic rays and fundamental physics of the compact sources. The Cherenkov Telescope Array (CTA) has a broad energy range from 30 GeV to 300 TeV, which arise the possibility to detect Pevatron candidates through pion production and consecutive gamma-decay processes. Among the Galactic TeV sources, SNRs are one of the most promising candidates since they are strong particle accelerators. Therefore, we use the Data Challenge One (DC-1) to search for possible PeVatron candidates. Fitting the data to different radiative processes, we find that RX J1713.7-3946 and HESS J1614-518 are promising sources with considerable flux due to pion-decay processes.
