| Description | Recently, very high energy TeV gamma-rays have been detected from the extended source W50/SS433 using the High-Altitude Water Cherenkov Observatory (HAWC). Multi-wavelength observations suggest that the extended lobes of W50 are being impacted by the SS433 jets tens of parsecs away. X-ray emission is found to fill the radio lobe out to the radio .ears., softening away from the black hole and with evidence of hard X-rays in the innermost regions pointing to an extreme accelerator. 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-ray emission, providing a key insight into the nature of this Galactic PeVatron. |

| 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. |
