Title Long term XMM-Newton and INTEGRAL monitoring of SGR1806-20 after the Giant Flare


DOI https://doi.org/10.5270/esa-k8hl4s2
Description In December 2004 SGR 1806-20 emitted the most powerful giant flare ever observed from a Soft Gamma-ray Repeater. This probably involved a large scale rearrangement of the magnetosphere leading to observable variations in the properties of its persistent X-ray emission. Comparison of the pre-flare observations with those obtained after this event supports the model of a magnetar with a twisted magnetosphere. We propose to continue our XMM-Newton monitoring of SGR 1806-20, complemented by INTEGRAL observations, in order 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.
