The long-awaited HAWC discovery of TeV gamma-ray emission from the eastern andwestern lobes of W50 nebula, powered by the microquasar SS433, was the firstevidence that accreting X-ray binaries can efficiently accelerate particles toTeV-PeV energies, indicating a new class of Galactic PeVatrons. The proposedNuSTAR and XMM observations will complete a broad-band X-ray survey of theparticle acceleration and jet termination sites of the W50/SS433 system.Spatially-resolved X-ray spectroscopy will resolve the non-thermal X-rayemission, characterize thermal X-ray knots in the western lobe and constrain thejet acceleration efficiency. Our multi-wavelength approach with the proposedobservations will provide deep insights to this unique mini-AGN jet interacting with the W50 nebula.

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.
