Scientific paper

On 27 Dec 2004, SGR 1806-20 emitted a giant flare, a once in a century event with an X-ray peak flux of at least 0.8 erg/cm^2 s. Seven days later we identified with VLA a bright (172 mJy, 1.4 GHz) expanding radio source at the location of the SGR, ~500 times brighter than the radio afterglow seen from SGR 1900+14 following the 1998 August 27 flare. We obtained data with MERLIN separated by 3 days, which show that within 13 days of the flare a radio structure of angular extent ~100 mas has formed with the peak of the flux displaced ~100 mas between the two epochs. This elongation immediately suggests a jet inclined to the line of sight and significantly relativistic, in analogy with X-ray emission from X-ray binary jets, which have reheated themselves presumably by the transfer of bulk kinetic energy to electrons. Discovery of an X-ray jet in a magnetar will provide unique evidence for the energetics of the shock, the ambient medium and the B-field of the pulsar.
