Description 2HWC J1928+177 is a bright Galactic gamma-ray source detected up to 100 TeV. It is a peculiar HAWC source, as VERITAS and HESS failed to detect its gamma-ray emission and there is no SNR or PWN nearby. At the HAWC source position, there is a variable X-ray source, potentially associated with a bright IR source. The non-thermal X-ray spectrum and the lack of aperiodic variability indicate that it is a TeV gamma-ray binary. XMM will determine the nature of the X-ray counterpart candidate, constrain its X-ray variability pattern for future TeV observations and search for other X-ray sources. If the X-ray counterpart candidate is not a TeV gamma-ray binary and no diffuse X-ray emission is found, the HAWC source would be the most remarkable dark accelerator with no counterpart below 10 TeV.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
