Description One of the most interesting discoveries of the Spitzer telescope is the existence of a dust clouds near the supernova remnant Cas A that appear to move with a velocity close to the speed of light. The likely explanation is that these dust clouds are not moving, but that a very luminous light flash is briefly lighting up high density dust clouds. The probable origin of the light flash is a giant flare from the central point source of Cas A, similar to flare from soft gamma ray repeaters. We propose to obtain X-ray images of the dust clouds to look for Fe-K fluorescence emission at 6.4virgulkeV, which would establish that the origin of the infrared emission is indeed a bright X-ray flare. This in turn would establish that the point source is a magnetar.

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.
