In a short DDT XMM observation of the magnetar Swift J1834.9-0846 we havediscovered extended emission with very peculiar properties. The most probableinterpretation is a wind nebula powered by the ultra-strong magnetic field ofthe source. The nebula shows striking asymmetric morphology and a soft spectrumunusual for a pulsar-wind nebula (PWN). The magnetar and its nebula are locatedwithin an SNR W41 and embedded in a field with TeV and GeV high energy sourceswhose origin is unknown. We propose a total of 150 ks observation for a detailedstudy of the nebula and the field sources. The nebula is the strongest-to-datecandidate for an elusive Magnetar Wind Nebula (MWN)

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.
