|Title||Search for the SNR signatures in W50 that harbors the microquasar SS 433|
|Author||Dr Ping Zhou|
|Description||It is a debated topic whether the very massive stars end their lives with supernova explosions or not. Finding a supernova remnant (SNR) hosting a black hole can provide direct evidence for the former scenario. SS 433, in the giant bubble W50, is a paradigmatic micro-quasar containing a virgul16Msun black hole. Its SNR has not been firmly established, as its energetic jets are considered as the major source to produce W50. The ROSAT image shows thermal structures in the north of W50, which are far from the jet precession cone. We propose 72 ks XMM- Newton observation toward the northern shell of W50, aiming to find signatures of a SNR and to study the explosion mechanism of SS433 s supernova. A non- detection would provide evidence that multiple episodes of jets in the past.|

|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.
