GRB 221009A/SN 2022xiw: A Supernova Obscured by a Gamma-Ray Burst Afterglow?
De-Feng Kong, Xiang-Gao Wang, WeiKang Zheng +10
We present optical photometry for the afterglow of GRB 221009A, in some respects the most extraordinary gamma-ray burst (GRB) ever observed. Good quality in the R-band light curve…
Revisit the Emission Polarization of the Internal-shock for the blazars' Jet
Hao-Qiang Zhang, Da-Bin Lin, Kuan Liu +1
Recent Imaging X-ray Polarimetry Explorer (IXPE) observations of blazars tend to support the shock model for the X-ray emission, but report a low polarization degree ()…
Searching for Associations Between Short Gamma-ray Bursts and Fast Radio Burst
Ming-Xuan Lu, Long Li, Xiang-Gao Wang +4
The physical origin of fast radio bursts (FRBs) is still unclear. However, young magnetars associated with short-duration gamma-ray bursts (SGRBs) have been thought to be possible…
Central Engine of Late-Time X-ray Flares with Internal Origin
Hui-Jun Mu, Wei-Min Gu, Shu-Jin Hou +5
This work focuses on a sample of seven extremely late-time X-ray flares with peak time , among which two flares can be confirmed as the late-time activity…
Variabilities of Gamma-ray Bursts from Black Hole Hyper-accretion Disks
Da-Bin Lin, Zu-Jia Lu, Hui-Jun Mu +5
The emission from black hole binaries (BHBs) and active galactic nuclei (AGNs) displays significant aperiodic variabilities. The most promising explanation for these variabilities…
The History of GRB Outflows: Ejection Lorentz Factor and Radiation Location of X-Ray Flares
Hui-Jun Mu, Da-Bin Lin, Shao-Qiang Xi +6
We present time-resolved spectral analysis of the steep decay segments of 29 bright X-ray flares of gamma-ray bursts (GRBs) observed with the Swift/X-ray telescope, and model their…
