| Abstract | We propose an observation of the western edge region of W50 nebula hosting themicroquasar SS 433.It is still unclear whether W50 is produced by the interaction between the jetsand the supernova remnant of the SS 433 birth, or by just the SS 433 jetsthemselves.The prime aim is to reveal the formation mechanism of W50 by distinguishingbetween thermal and non-thermal (synchrotron) emissions in the edge region ofW50.The second aim is to understand the particle acceleration processes in the jetpropagating in the nebula. We recently found a hint of particle re-acceleration occurring at the knot existing in the western jet. Using the large collecting area of XMM, we make the re-acceleration clear by determining the change of the spectral slope of the synchrotron emission along the jet. |

| 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. |
