Variabilities of Gamma-ray Bursts from the Dynamics of Fallback Material after Tidal Disruption
Yun-Peng Li, Da-Bin Lin, Guo-Yu Li +2
The gamma-ray burst (GRB) GRB 211211A and GRB 060614, believed to originate from the merger of compact objects, exhibit similarities to the jetted tidal disruption event (TDE) Sw J…
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…
A Comprehensive Analysis of Insight-HXMT Gamma-Ray Burst Data. I. Power Density Spectrum
Zi-Min Zhou, Xiang-Gao Wang, En-Wei Liang +7
Power Density Spectrum (PDS) is one of the powerful tools to study light curves of gamma-ray bursts (GRBs). We show the average PDS and individual PDS analysis with {\it Hard X-ray…
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…
SN 2019tua : A Type IIb Supernova with Multiple Bumps in the Light Curves
Xin-Bo Huang, Xiang-Gao Wang, Long Li +9
We present photometric and spectroscopic observations and analysis of the type IIb supernova (SN) SN 2019tua, which exhibits multiple bumps in its declining light curves between 40…
