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…

Gamma-Ray Bursts: Polarization of Afterglows from Two-Component Jets
X. F. Wu, Z. G. Dai, Y. F. Huang +1
Polarization behaviors of optical afterglows from two-component gamma-ray burst jets are investigated, assuming various configurations for the two components. In most cases, the ob…

Analytical light curves in the realistic model for GRB afterglows
X. F. Wu, Z. G. Dai, Y. F. Huang +1
(abridged) Afterglow light curves are constructed analytically for realistic gamma-ray burst remnants decelerating in either a homogeneous interstellar medium or a stellar wind env…
