| Abstract | 3HWC J1928+178 is one of the brightest Galactic gamma-ray sources detected byHAWCup to ~56 TeV and potentially associated with one of the dozen PeVatron sourcesdiscovered by LHAASO.Given no apparent pulsar wind nebula or supernova remnant in the vicinity, theHAWC sourcestill remains unidentified. Recent X-ray and TeV observations as well as ourmulti-wavelength SED studypinned down the HAWC source to be either a PeVatron pulsar wind nebula, TeV haloor TeV gamma-ray binary. In particular, we found two X-ray counterpart candidates of the HAWC source - a variable X-ray source with a massive companion and putative diffuse X-ray emission. We propose a follow-up XMM observation of the X-ray counterpart candidates for determining the nature of this enigmatic HAWC source. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
