Title Long term monitoring of SGR 1806-20 after the Giant Flare

Author Dr Sandro Mereghetti
Description SGR 1806-20 has recently emitted the most powerful Giant Flare ever observed from a Soft Gamma-ray Repeater. This involved a large scale restructuring of the magnetosphere leading to observable variations in the properties of its persistent X-ray emission. Comparison of the pre-flare XMM-Newton observations with two recent TOO pointings support a magnetar scenario in which the effects of a twisted magnetosphere are considered. We propose to continue the monitoring of SGR 1806-20 to study the long term effects of the Giant Flare and how the source evolves toward quiescence after this "once-in-a-lifetime" event.

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.
