Constraining the origin of TeV photons from gamma-ray bursts with delayed MeV-GeV emission formed by interaction with cosmic infrared/microwave background photons
X. Y. Wang, K. S. Cheng, Z. G. Dai +1
It has been suggested that electromagnetic cascade of very high energy gamma-rays from gamma-ray bursts (GRBs) in the infrared/microwave background can produce delayed MeV-GeV phot…
GRB afterglows in the deep Newtonian phase
Y. F. Huang, K. S. Cheng, Z. G. Dai +1
In many GRBs, afterglows have been observed for months or even years. It deserves noting that at such late stages, the remnants should have entered the deep Newtonian phase, during…
Rebrightening of XRF 030723: further evidence for a two-component jet in gamma-ray burst
Y. F. Huang, X. F. Wu, Z. G. Dai +2
Optical afterglows from two-component jets under various configurations are investigated numerically. Generally, the light curve is characterized by a rapid rebrightening when the…
Temporal variability in early afterglows of short gamma-ray bursts
Zhuo Li, Z. G. Dai, T. Lu
The shock model has successfully explained the observed behaviors of afterglows from long gamma-ray bursts (GRBs). Here we use it to investigate the so-called early afterglows from…
Pair loading in Gamma-Ray Burst Fireball And Prompt Emission From Pair-Rich Reverse Shock
Zhuo Li, Z. G. Dai, T. Lu +1
Gamma-ray bursts (GRBs) are believed to originate from ultra-relativistic winds/fireballs to avoid the "compactness problem". However, the most energetic photons in GRBs may still…
Relativistic Wind Bubbles and Afterglow Signatures
Z. G. Dai
Highly magnetized, rapidly rotating compact objects are widely argued as central energy sources of -ray bursts (GRBs). After the GRB, such a magnetar-like object may directly lo…
