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…
Single-pulse-based interstellar scintillation studies of RRATs
Zi-wei Wu, Wei-wei Zhu, Zi-yao Fang +16
The nature of irregularly spaced pulses of rotating radio transients (RRATs) complicates interstellar scintillation studies. In this letter, we report the primary scintillation par…
The Host Galaxy of the Hyperactive Repeating FRB 20240114A: Behind a Galaxy Cluster
Xiang-Lei Chen, Chao-Wei Tsai, Di Li +16
We report on the optical spectroscopic observations of the host galaxy of the hyperactive repeating fast radio burst, FRB 20240114A. The host galaxy is a dwarf galaxy at a redshift…
Hyper-active repeating fast radio bursts from rotation modulated starquakes on magnetars
Jia-Wei Luo, Jia-Rui Niu, Wei-Yang Wang +13
The non-detection of periodicity related to rotation challenges magnetar models for fast radio bursts (FRBs) with FRB emission from close to the magnetar surface. Moreover, a bimod…
Propagation-induced Frequency-dependent Polarization Properties of Fast Radio Burst
Wei-Yang Wang, Xiaohui Liu, Dongzi Li +6
Frequency-dependent polarization properties provide crucial insights into the radiation mechanisms and magnetic environments of fast radio bursts (FRBs). We explore an analytical s…
