In December 2004, the soft gamma-ray repeater SGR 1806-20 emitted the most powerful giant flare ever observed. This probably involved a large-scale rearrangement of the magnetosphere leading to observable variations in the properties of its X-ray emission. Here we present the results of the first Suzaku observation of SGR 1806-20, together with almost simultaneous observations with XMM-Newton and INTEGRAL. The source seems to have reached a state characterized by a flux close to the pre-flare… Expand

An expanding radio nebula produced by a giant flare from the magnetar SGR 1806–20
From day 6 to day 19 after the flare from SGR 1806 - 20, a resolved, linearly polarized, radio nebula was seen, expanding at approximately a quarter of the speed of light, and to create this nebula, at least 4 × 1043 ergs of energy must have been emitted by the giant flare. Expand
Detection of a radio counterpart to the 27 December 2004 giant flare from SGR 1806–20
The energetics and the rapid decay of the radio source are not compatible with the afterglow model that is usually invoked for γ-ray bursts, and it is suggested that the rapidly decaying radio emission arises from the debris ejected during the explosion. Expand
