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…
Diverse Morphologies of GRB X-Ray Plateaus within a Common Magnetar Framework
Xiao-Fei Dong, Yong-Feng Huang, Nurimangul Nurmamat +7
The origin of the X-ray plateau phase in gamma-ray bursts (GRBs) remains an open problem. In particular, it is unclear whether GRBs with different temporal morphologies (i.e., with…
Constraining the Supernova Remnant Environment of FRB 190520B with Dispersion Measure and Scattering Timescale
Jia-Peng Wei, Chen Deng, Gwenael Giacinti +4
FRB 190520B is a repeating fast radio burst source whose large dispersion measure (DM) and temporal broadening suggest a dense and evolving local environment. In this work, we test…
Gamma-Ray Bursts: Evidence for a Common Origin of X-ray Plateaus with Diverse Temporal Decay Index
Xiao-Fei Dong, Yong-Feng Huang, Chen Deng +8
A significant fraction of gamma-ray bursts (GRBs) exhibit a plateau in the early X-ray afterglow light curve, whose mechanism remains uncertain. While the post-plateau normal decay…
A Statistical Analysis of Fluence and Energy Distributions of Non-repeating Fast Radio Bursts Detected by CHIME
Nurimangul Nurmamat, Yong-Feng Huang, Xiao-Fei Dong +6
Fast Radio Bursts (FRBs) are energetic radio bursts that typically last for milliseconds. They are mostly of extragalactic origin, but the progenitors, trigger mechanisms and radia…
Magnetic Reconnection as a Potential Driver of X-ray Variability in Active Galactic Nuclei
Chen-Ran Hu, Yong-Feng Huang, Lang Cui +13
We present a systematic analysis on the X-ray variability in 13 bright quasars at z > 4.5, combining recent Swift observations from 2021 to 2023 and archival multi-epoch observatio…
A Statistical Study of the Gamma-Ray Burst and Supernova Association
Xiao-Fei Dong, Yong-Feng Huang, Zhi-Bin Zhang +5
The association between long gamma-ray bursts (LGRBs) and core-collapse supernovae (SNe) has been well established since the discovery of SN 1998bw, which was linked to the low-lum…
Decoding FRB Energetics and Frequency Features Hidden by Observational Incompleteness
Chen-Ran Hu, Yong-Feng Huang, Jin-Jun Geng +9
Fast radio bursts (FRBs) are millisecond-duration extragalactic radio flashes likely powered by magnetars, yet their radiation mechanism remains unknown. Limited sensitivity and fi…
A second-scale periodicity in an active repeating fast radio burst source
Chen Du, Yong-Feng Huang, Jin-Jun Geng +14
Fast radio bursts (FRBs) are fierce radio flashes from the deep sky. Abundant observations have indicated that highly magnetized neutron stars might be involved in these energetic…
