Abstract

LHAASO J1849-0003 is one of the twelve gamma-ray sources that can emit photons above 100 TeV reported by LHAASO in 2021. It is spatially coincident with HESS J1849-000, which may be powered by PSR J1849-0001. The High Altitude Water Cherenkov (HAWC) observatory has also observed a possible counterpart source named eHWC J1850+001 above 56 TeV. In this work, we use the most up-to-date HAWC dataset with 2398 days of data to perform dedicated multi-source modeling of the region around eHWC J1850+001. We present the spectrum and morphology of eHWC J1850+001 and other nearby sources identified during a systematic source search. We anticipate the HAWC observational results to determine a potential connection between HESS J1849-000 and LHAASO J1849-0003, providing a more complete TeV spectral study of this energetic source.
