Evidence of self-organized criticality in the prompt emission of a bright gamma-ray burst
Wen-Long Zhang, Wen-Jun Tan, Hao-Tian Lan +18
Gamma-ray bursts (GRBs) are the most energetic explosive events in the Universe, yet the physical mechanism of their prompt emission remains a mystery. Especially, it is unclear wh…
Propagation Diagnostics of Supernova Remnant Environments around Young Repeating FRBs. I. Hydrodynamic Evolution of the Source-Local Dispersion Measure
Xiang-Er Fang, Zhen-Yin Zhao, Yi-Qing Lin +2
Repeating fast radio bursts may reside in young supernova remnant (SNR) environments whose evolving plasma contributes to the observed dispersion measure (DM). We use two-dimension…
Periodic Emission Frequency Modulation in a Hyperactive Fast Radio Burst
Rui-Nan Li, Hao-Tian Lan, Zhen-Yin Zhao +3
Fast radio bursts (FRBs) are intense, short-duration radio transients of mysterious origin. They have been detected across a wide range of frequencies from 110 MHz to 8 GHz. Their…
The disk precession in a Be star-magnetar binary and its application to the rotation measure of FRB 20201124A
Ying-ze Shan, Wei-Hua Lei, Hao-Tian Lan +7
Fast radio bursts (FRBs) are bright, millisecond-duration radio bursts with poorly known origins. Most FRB sources are detected only once, while some are repeaters. Variation patte…
A unified model of active repeating fast radio bursts associated with persistent radio sources
F. Y. Wang, H. T. Lan, Z. Y. Zhao +5
Fast radio bursts (FRBs) are intense pulses with unknown origins. A subclass of repeating FRBs show some common features, such as associated compact persistent radio sources (PRSs)…
