Abstract
2HWC J1928+177 is a source recently discovered at TeV energies in the second HAWC catalog.
It is coincident with the Fermi unidentified source 3FGL J1928+1739 and the pulsar PSR J1928+1746, which is 83 kyr old and located at a distance of 5 kpc with an Edot=1.6 x 10^{36} erg/s. 2HWC J1928+177 is not detected by any of the IACTs currently in operation, which puts strong constrains on the morphology and spectrum of the source. There is no sign of shell-like structure in the region at other wavelengths, which in addition to the presence of a pulsar at the center, points to a Pulsar Wind Nebula origin of the TeV emission. We present a dedicated morphological and spectral analysis of the region using HAWC and H.E.S.S. data to unveil the nature of the source and study its properties.
