GRB 251222A is a long-duration gamma-ray burst at a spectroscopic redshift of . It was detected by the EP as the soft X-ray transient EP251222b before and during the gamma…
Are Repeaters Prevalent Among the Known Fast Radio Burst Sources?
Xiao-Fei Dong, Qing Pan, Yong-Feng Huang +10
Fast radio bursts (FRBs) are millisecond radio pulses of unknown origin. Despite extensive follow-up observations, only of FRBs have been confirmed as repeaters. It remai…
Multiwavelength Observations of the Apparently Non-repeating FRB 20250316A
Ye Li, Hui Sun, Lei Qian +72
The physical origin of fast radio bursts (FRBs) remains uncertain. Although multiwavelength observations have been widely conducted, only Galactic FRB~20200428D is associated with…
Anisotropy of core-collapse supernovae effected by AGN disks
Jiao-Zhen She, Tong Liu, Bao-Quan Huang +4
Active galactic nucleus (AGN) disk provide dense environments to influence on the star formation, evolution, and migration. In AGN disks, pressure gradients and migration accelerat…
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…
EP241021a: a months-duration X-ray transient with luminous optical and radio emission
Shu Xinwen, Yang Lei, Yang Haonan +82
We present the discovery of a peculiar X-ray transient, EP241021a, by the Einstein Probe (EP) mission, and the results from multiwavelength follow-up observations. The transient wa…
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…
Quasi-thermal Photosphere Emission from Structured Jets of Gamma-Ray Bursts
Ding-Fang Hu, Jin-Jun Geng, Hao-Xuan Gao +2
The prompt emission of gamma-ray bursts (GRBs) is supposed to be released from the relativistic jet launched from the central engine. Apart from the non-thermal nature of the spect…
Extreme superluminal expansion traces an ultra-narrow GRB jet across relativistic regimes
Jin-Jun Geng, Ying-Kang Zhang, Hao-Xuan Gao +20
The long-term evolution of gamma-ray burst (GRB) jets from ultra-relativistic launch to a slowly expanding radio source remains a fundamental problem in high-energy astrophysics, r…
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…
