Jet break time -- flux density relationship and constraints on physical parameters of GRB afterglows
X. F. Wu, Z. G. Dai, E. W. Liang
We derive a relation between the flux density at the light-curve break of a gamma-ray burst (GRB) afterglow and the break time . The break is due to the transition…

The Luminosity - E_p Relation within Gamma--Ray Bursts and Implications for Fireball Models
E. W. Liang, Z. G. Dai, X. F. Wu
Using a sample of 2408 time-resolved spectra for 91 BATSE gamma-ray bursts (GRBs) presented by Preece et al., we show that the relation between the isotropic-equivalent luminosity…

Strong GeV Emission Accompanying TeV Blazar H1426+428
Y. Z. Fan, Z. G. Dai, D. M. Wei
For High frequency BL Lac objects (HBLs) like H1426+428, a significant fraction of their TeV gamma-rays emitted are likely to be absorbed in interactions with the diffuse IR backgr…
