Recently, very high energy TeV gamma-rays have been detected from the extendedsource W50/SS433 using the High-Altitude Water Cherenkov Observatory (HAWC).Multi-wavelength observations suggest that the extended lobes of W50 are beingimpacted by the SS433 jets tens of parsecs away. X-ray emission is found to fillthe radio lobe out to the radio .ears., softening away from the black hole andwith evidence of hard X-rays in the innermost regions pointing to an extremeaccelerator. We propose a joint XMM/NuSTAR observation of the HAWC emission,coincident with the inner eastern lobe of W50. This broadband X-ray study will,for the first time, resolve and constrain both the non-thermal and thermal X-rayemission, providing a key insight into the nature of this Galactic PeVatron.

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.
