Detailed Morphology study of 3HWC J1857+027 region with HAWC data and comparison with H.E.S.S. results

3HWC J1857+027 has remained unidentified but is a pulsar wind nebula (PWN) candidate in the 3HWC catalog made by the High-Altitude Water Cherenkov Gamma-Ray Observatory (HAWC). In this region, the High Energy Stereoscopic System (H.E.S.S.) resolved two extended sources: HESS J1857+027 and HESS J1858+020, which are separated by half a degree. The multi-source fitting method based on the Multi-Mission Maximum Likelihood framework (3ML) is used to model and analysis the emission from this region in about five and half years of HAWC data. With improved performance and more accumulated statistics, we can disentangle two extended sources in the region. I will present an analysis of the gamma-ray emission in this region beyond tens of TeV.
