Description
Located in the southern field of view of the High Altitude Water Cherenkov (HAWC) observatory, the eHWC J1825-134 region is one of the most complicated gamma-ray emission sites on the galactic plane. The region contains a few PeVatron candidates that can accelerate particles up to PeV energies. Disentangling the overlapping gamma-ray emission and associating it with accelerators is crucial to understanding the mechanism of cosmic-ray acceleration and gamma-ray production near the accelerators. In this talk, I will present the ultra-high-energy gamma-ray emission observed near the powerful pulsar PSR J1826-1334 and the surrounding larger extended gamma-ray emission. The large extended gamma-ray emission may indicate that the system is transitioning to a TeV halo, where electrons begin to diffuse through the interstellar medium.
