Description
High-luminosity “Pevatrons” exist in our galaxy, according to observations made with the Large High Altitude Air Shower Observatory (LHAASO). This work analyzes two notable sources, LHAASO J1825-1326 and LHAASO J1839-0545. The low angular resolution of the LHAASO devices indicates two alternative origins for each PeVatron. 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 PSR J1838-0537. Using the Gammapy Python package, we examine the capability of the Cherenkov Telescope Array Observatory (CTAO) to determine the origins of the LHAASO observations. By combining data from the Fermi large area telescope (Fermi-LAT), High Energy Stereoscopic System (HESS), and High-Altitude Water Cherenkov (HAWC), we estimate the source's spectrum from each region. To evaluate the capability of CTAO to detect gamma-ray emissions coming from these regions, we employed the 1D ON/OFF observation technique. The findings suggest that CTAO can identify the origins of the LHAASO observations.
