X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
Gamma-ray Bursts in the Radio Sky: the Role of the SKA-VLBI
Stefano Giarratana, Om Sharan Salafia, Xue-Feng Wu +6
Radio observations of -ray bursts (GRBs) employing the very long baseline interferometry (VLBI) technique provide us with fundamental information on the dynamics and the geomet…
Pinning Down the Geometry of the Type Ic Broad-Line Supernova 2026gzf
Xudong Wen, Yi Yang, Jing Lu +11
Type Ic broad-line supernovae (SNe Ic-BL) are often associated with energetic explosions that display a prompt outburst of high-energy emission. Since their progenitor lost the H a…
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…
The Formation Rate and Luminosity Function of Fast X-ray transients from Einstein probe
Yizhou Guo, Houdun Zeng, Junjie Wei +4
Following its launch on 2024 January 9, the Einstein Probe (EP) telescope has detected hundreds of fast X-ray transients (FXTs), yet their physical origins remain elusive. Understa…
Intrinsic Pulse Widths of FRB 20121102A and Calculation of Broadening from Propagation and Instrumental Effects
Jia-Peng Wei, Yong-Feng Huang, Lang Cui +3
The pulse widths of fast radio bursts are always broadened due to the scattering of the plasma medium through which the electromagnetic wave passes. The recorded pulse width will b…
