| Abstract | Supernova remnants and pulsar nebulae with unusual morphologies indicatecomplicated interactions with their surroundings, demonstrating the wide varietyof conditions into which supernovae explode. G357.7-0.1 (the Tornado) is anextraordinary example of such a source - there has been heated debate as towhether its bizarre radio appearance corresponds to a supernova remnant, apulsar nebula, or even an exotic accreting system. We have recently detectedfaint extended X-ray emission from this system with Chandra, the data from whichseem to be best explained by a thermal spectrum characteristic of shock-heatedgas. From these properties, we tentatively propose that the Tornado is asupernova remnant. We here propose deeper XMM observations to test this claim. |

| 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. |
