A Unified Model for the Emission of Supernova-Associated Fast X-ray Transients: Case Studies of EP240414a, EP250108a, and GRB~171205A
Yu-Fei Li, Da-Bin Lin, Jia Ren +2
The Einstein Probe (EP) has detected several Fast X-ray Transients (FXTs) associated with broad-lined Type Ic supernovae (SNe), including EP240414a and EP250108a. The observations…
GRB 250424A: A Case Study of Energy Injection with Multiwavelength Observations
Yifang Liang, Yun Wang, WeiKang Zheng +61
We present a comprehensive multiwavelength analysis of the long-duration gamma-ray burst (GRB) 250424A. Our dataset spans from the prompt gamma-ray emission to late-time optical mo…
Revealing the high redshift host galaxy of the short GRB 061201 with JWST
Yuhan Mao, Hanrui He, Jia Ren +6
Using deep near-infrared and optical images from JWST and HST, we identify a new host galaxy candidate for GRB 061201. It lies ~2" from the optical afterglow position. Photometric…
The Double-Burst Nature and Early Afterglow Evolution of Long GRB 110801A
Qiu-Li Wang, Hao Zhou, Yun Wang +3
We present a comprehensive temporal and spectral analysis of the long-duration gamma-ray burst GRB 110801A, utilizing multi-band data from the Neil Gehrels Swift Observatory and gr…
Short-duration GRB 250221A Afterglow Driven by Two-Component Jets from the merger of a compact star
Xiao Tian, Hou-Jun Lü, Xiao-Xuan Liu +4
GRB 250221A is a short gamma-ray burst (GRB) at redshift , with a duration of 1.8 s and no extended emission in either Swift/Burst Alert Telescope or Konus-Wind bands. A r…
Stellar Wind-Blown Bubbles as Environments for Late-Time Rebrightening of Gamma-Ray Burst Afterglows
Jia Ren, Xiao-Yan Li, Yun Wang +5
We presented the multi-wavelength afterglow fitting results for three events that exhibit late afterglow rebrightening behavior: EP240414a (), GRB 240529A (), and…
