No Strong Evidence for Plasma Lensing in FRB 20240114A
Jiarui Niu, Xiaohui Liu, Nan Xu +33
FRB~20240114A is an extremely active repeating fast radio burst for which plasma lensing has been proposed to explain its burst-rate variations, spectral evolution, and apparently…
Resolving the 2024 Outburst of Magnetar 1E 1841-045 from its host Supernova Remnant with EP-FXT
Yu-Cong Fu, Lin Lin, Yu-Jia Zheng +11
The magnetar 1E 1841-045 exhibited a new active episode starting on August 20, 2024, marked by X-ray bursts and enhanced persistent emission. Using data from the Einstein Probe (EP…
Investigating FRB 20240114A with FAST: Morphological Classification and Drifting Rate Measurements in a Burst-Cluster Framework
Long-Xuan Zhang, Shiyan Tian, Junyi Shen +59
This study investigates the morphological classification and drifting rate measurement of the repeating fast radio burst (FRB) source FRB 20240114A using the Five-hundred-meter Ape…
A comprehensive search for Long and Short Periodic Features from an Extremely Active Cycle of FRB 20240114A
Dengke Zhou, Pei Wang, Jianhua Fang +56
Possible periodic features in fast radio bursts (FRBs) may provide insights into their astrophysical origins. Using extensive observations from the Five-hundred-meter Aperture Sphe…
The magnetar model's energy crisis for a prolific repeating fast radio burst source
Jun-Shuo Zhang, Tian-Cong Wang, Pei Wang +61
Fast radio bursts (FRBs) are widely considered to originate from magnetars that power the explosion through releasing magnetic energy. Active repeating FRBs have been seen to produ…
Periodic variation of magnetoionic environment of a fast radio burst source
Jiangwei Xu, Heng Xu, Yanjun Guo +8
Fast radio bursts (FRBs) are luminous, dispersed millisecond-duration radio bursts whose origin is poorly known. Recent observations suggest that some FRBs may reside in binary sys…
