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…
Constraining the Cosmological Parameters and Transition Redshift with Gamma-Ray Bursts and Supernovae
F. Y. Wang, Z. G. Dai
A new method of measuring cosmology with gamma-ray bursts(GRBs) has been proposed by Liang and Zhang recently. In this method, only observable quantities including the rest frame p…
Is GRB 050904 a super-long burst?
Y. C. Zou, Z. G. Dai, D. Xu
By considering synchrotron radiative process in the internal shock model and assuming that all internal shocks are nearly equally energetic, we analyze the gamma-ray burst (GRB) em…
Early Afterglows in Wind Environments Revisited
Y. C. Zou, X. F. Wu, Z. G. Dai
When a cold shell sweeps up the ambient medium, a forward shock and a reverse shock will form. We analyze the reverse-forward shocks in a wind environment, including their dynamics…
Testing Gamma-Ray Burst Jet Structure with the Distribution of Gamma-Ray Energy Release
L. Xu, X. F. Wu, Z. G. Dai
We present a general method for testing gamma-ray burst (GRB) jet structure and carry out a comprehensive analysis about the prevalent jet structure models. According to the jet an…
A Reverse-Shock Model for the Early Afterglow of GRB 050525A
L. Shao, Z. G. Dai
The prompt localization of gamma-ray burst (GRB) 050525A by {\em Swift} allowed the rapid follow-up of the afterglow. The observations revealed that the optical afterglow had a maj…
