Descrição
High-luminosity PeVatrons exist in our galaxy, according to observations made with LHAASO. In this work, we analyze two notable sources, LHAASO J1825-1326 and LHAASO J1839-0545. Two alternative origins for each PeVatron are indicated by the low angular resolution of the LHAASO devices. LHAASO J1825-1326 may have originated from the pulsars PSR J1826-1334 and PSR J1826-1256, whereas LHAASO J1839-0545 may have originated from the pulsars PSR J1837-0604 and J1838-0537. We estimate the source’s spectrum from the source regions (LHAASO J1825-1326 and LHAASO J1839-0545) by combining data from the Fermi-LAT, HESS, HAWC, and LHAASO instruments. To evaluate the capability of CTAO to detect gamma-ray emissions coming from these regions, we employed the 1D ON/OFF observation technique. According to the results, CTAO might be able to identify these sources.
