The X-ray emission lines in GRB afterglows: the evidence for the two-component jet model
W. H. Gao, D. M. Wei
Recently, X-ray emission lines have been observed in X-ray afterglows of several -ray bursts. It is a major breakthrough for understanding the nature of the progenitors. It is p…

Are there cosmological evolution trends on Gamma-Ray Burst features?
D. M. Wei, W. H. Gao
The variability of gamma-ray burst (GRB) is thought to be correlated with its absolute peak luminosity, and this relation had been used to derive an estimate of the redshifts of GR…
