Abstract
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 understand the mechanism of cosmic-ray acceleration and gamma-ray
production near the accelerators. In this talk, I will present each of the gamma-ray sources resolved
in this region using 1910 days of HAWC data, including their spectra. Also, we have studied their
potential association with astrophysical accelerators, the binary system LS 5039, two pulsar wind
nebulae, and a young star cluster.
