GRB 170519A: Thermal Radiation in an X-ray Flare and Decaying Magnetic Fields for the Early-Time Afterglow
Zi-Min Zhou, Liang-Jun Chen, Rui-Quan Li +5
GRB 170519A was discovered by \emph{Swift}/BAT, and then observed by \emph{Swift}/XRT, \emph{Swift}/UVOT, and ground-based telescopes. We report Lick/KAIT observations of GRB 17051…

Spectral Lag for a Radiating Jet Shell with a High Energy Cut-off Radiation Spectrum
Shen-Shi Du, Da-Bin Lin, Rui-Jing Lu +5
Recent research shows that the spectral lag is closely related to the spectral evolution in GRBs. In this paper, we study the spectral lag for a radiating jet shell with a high-ene…
