Rapid fading of optical afterglows as evidence for beaming in gamma-ray bursts
Y. F. Huang, Z. G. Dai, T. Lu
Based on the refined dynamical model proposed by us earlier for beamed -ray burst ejecta, we carry out detailed numerical procedure to study those -ray bursts with rapidly fa…

Gamma-ray burst afterglows and evolution of postburst fireballs with energy injection from strongly magnetic millisecond pulsars
Z. G. Dai, T. Lu
Millisecond pulsars with strong magnetic fields may be formed through several processes, e.g. accretion-induced collapse of magnetized white dwarfs, merger of two neutron stars. Du…
