TeV Analysis of gamma-ray source 3HWC J1843-034

3HWC J1843-034 is one of the very-high-energy gamma-ray sources that has been observed at above 56 TeV by the High Altitude Water Cherenkov (HAWC) Observatory. This source coincides with LHAASO J1843-0338, which may be associated SNR G28.6-0.1. In this work, we systematically model this source confused region with the most up-to-date HAWC data to study the morphology and spectrum of 3HWC J1843-034. Also, we compare our results with other gamma-ray experiments of various energies.
