Do Prompt Gamma-ray Burst Fireball Composition Impact on Afterglow Emission? Cases Study for Long GRBs 080916C/090902B and Short GRBs 090510/130603B
Yu Gan, Ren-Jie Xiong, Zi-Qi Wang +3
Broadband observations with the {\em Fermi} mission reveal that a large fraction of gamma-ray burst (GRB) spectra are dominated by non-thermal emission, while a small fraction are…
Probing the Nature of High-Redshift Long GRB 250114A and Its Magnetar Central Engine
Wen-Yuan Yu, Hou-Jun Lü, Xiao Tian +2
GRB 250114A is a long-duration gamma-ray burst (GRB) which triggered the Swift/BAT with a spectroscopic high-redshift at . The light curve of the prompt emission is comp…
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…
Multiwavelength Polarization Observations of Mrk 501
Xin-Ke Hu, Yu-Wei Yu, Jin Zhang +18
Mrk 501 is a prototypical high-synchrotron-peaked blazar (HBL) and serves as one of the primary targets for the {\it Imaging X-ray Polarimetry Explorer} ({\it IXPE}). In this study…
