X-ray flares: late internal and late external shocks
X. F. Wu, Z. G. Dai, X. Y. Wang +3
We analyze several recently detected gamma-ray bursts (GRBs) with late X-ray flares in the context of late internal shock and late external shock models. We find that the X-ray fla…
A Two-Component Explosion Model for the Giant Flare and Radio Afterglow from SGR1806-20
Z. G. Dai, X. F. Wu, X. Y. Wang +2
The brightest giant flare from the soft -ray repeater (SGR) 1806-20 was detected on 2004 December 27. The isotropic-equivalent energy release of this burst is at least one order…
An energetic blast wave from the December 27 giant flare of the soft gamma-ray repeater 1806-20
X. Y. Wang, X. F. Wu, Y. Z. Fan +2
Recent follow-up observations of the December 27 giant flare of SGR 1806-20 have detected a multiple-frequency radio afterglow from 240 MHz to 8.46 GHz, extending in time from a we…
External shock model for the large-scale, relativistic X-ray jets from the microquasar XTE J1550-564
X. Y. Wang, Z. G. Dai, T. Lu
Large-scale, decelerating, relativistic X-ray jets due to material ejected from the black-hole candidate X-ray transient and microquasar XTE J1550-564 has been recently discovered…
