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…

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…

Mass function of stellar black holes as revealed by the LIGO-Virgo-KAGRA observations

Xiao-Fei Dong, Yong-Feng Huang, Zhi-Bin Zhang +5

Ninety gravitational wave events have been detected by the LIGO-Virgo-KAGRA network and are released in the Gravitational-Wave Transient Catalog. Among these events, 83 cases are d…

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…

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 radio flashes of extragalactic origin, with magnetars implicated as viable central engines. Yet their triggering and radiation mec…

Softness Ratio of SWIFT Gamma-ray Bursts and Relevant Correlations

Fan Xu, Yong-Feng Huang, Liang Li +7

The properties of X-ray flashes (XRFs) and X-ray rich gamma-ray bursts (XRRs) as compared with classical gamma-ray bursts (C-GRBs) have been widely discussed during the \emph{Swift…

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 Comprehensive Analysis on Repeating Fast Radio Bursts

Chen-Ran Hu, Yong-Feng Huang

Nearly 700 fast radio burst (FRB) sources have been detected till now, among which 29 FRBs are found to burst out repeatedly. Although a firm connection between at least some FRBs…

GRB 240529A: A Tale of Two Shocks

Tian-Rui Sun, Jin-Jun Geng, Jing-Zhi Yan +66

Thanks to the rapidly increasing time-domain facilities, we are entering a golden era of research on gamma-ray bursts (GRBs). In this Letter, we report our observations of GRB 2405…

GRB Timing: Decoding the Hidden Slow Jets in GRB 060729

Jin-Jun Geng, Ding-Fang Hu, Hao-Xuan Gao +16

Gamma-ray bursts (GRBs) are luminous stellar explosions characterized by the ejection of relativistic jets. This work proposes a novel paradigm to study these GRB jets. By analyzin…

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…

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…

Axial current as the origin of quantum intrinsic orbital angular momentum

Orkash Amat, Nurimangul Nurmamat, Yong-Feng Huang +9

We show that the axial current density is the physical origin (generator) of quantum intrinsic orbital angular momentum (IOAM). Without the axial current, the IOAM of particles van…

Spreading and multi-wavelength emissions of an ultra-narrow relativistic jet from GRB 221009A

Jin-Jun Geng, Ying-Kang Zhang, Hao-Xuan Gao +19

The long-term evolution of relativistic jets in gamma-ray bursts (GRBs), particularly from days to months post-burst, remains a fundamental puzzle in astrophysics. Here, we report…

Two Periodic Activity Epochs in FRB 20201124A: Coincident with Critical RM Evolution Epochs and Its Implications

Wen-Long Zhang, Chen-Ran Hu, Chen Du +12

Recent observations of the repeating fast radio burst FRB 20201124A by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) revealed a second-scale periodic modulation…
