Structure in the radio counterpart to the 2004 Dec 27 giant flare from SGR 1806-20
R. P. Fender, T. W. B. Muxlow, M. A. Garrett +7
On Dec 27, 2004, the magnetar SGR 1806-20 underwent an enormous outburst resulting in the formation of an expanding, moving, and fading radio source. We report observations of this…
A Re-brightening of the Radio Nebula associated with the 2004 December 27 giant flare from SGR 1806--20
J. D. Gelfand, Y. E. Lyubarsky, D. Eichler +7
The 2004 Dec. 27 giant Gamma-ray flare detected from the magnetar SGR 1806-20 created an expanding radio nebula which we have monitored with the Australia Telescope Compact Array a…
Diagnosing the outflow from the SGR 1806-20 Giant Flare with Radio Observations
J. Granot, E. Ramirez-Ruiz, G. B. Taylor +6
On 2004 Dec. 27, the soft gamma repeater (SGR) 1806-20 emitted the brightest giant flare (GF) ever detected from an SGR, with an (isotropic) energy release times greater…
An expanding radio nebula produced by a giant flare from the magnetar SGR 1806-20
B. M. Gaensler, C. Kouveliotou, J. D. Gelfand +16
Soft gamma repeaters (SGRs) are "magnetars", a small class of slowly spinning neutron stars with extreme surface magnetic fields, ~10^15 gauss. On 2004 December 27, a giant flare w…
