An expanding radio nebula produced by a giant flare from the magnetar SGR 1806-20

Article Abstract:

The detection of a fading radio afterglow produced by the outburst of the magnetar soft-gamma repeaters (SGR) 1806-20, with a luminosity 500 times larger than the only other detection of a similar source, is reported. A resolved, linearly polarized, radio nebula is observed, expanding at approximately a quarter of the speed of light.

A giant gamma-ray flare from the magnetar SGR 1806-20

Article Abstract:

A report that stars-soft gamma-ray repeaters (SGR) 1806-20 emitted a giant flare on 27 December 2004 is presented. The total flare energy is 2*10(super 46) erg is released during a catastrophic reconfiguration of the neutron star's magnetic field.
