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…
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…
Multi-year Polarimetric Monitoring of Four CHIME-Discovered Repeating Fast Radio Bursts with FAST
Yi Feng, Yong-Kun Zhang, Jintao Xie +50
In this study, we report multi-year polarization measurements of four repeating FRBs initially discovered by CHIME: FRBs~20190117A, 20190208A, 20190303A, and 20190417A. We observed…
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 Chinese Pulsar Timing Array data release I. Single pulsar noise analysis
Siyuan Chen, Heng Xu, Yanjun Guo +23
The Chinese Pulsar Timing Array (CPTA) has collected observations from 57 millisecond pulsars using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) for close to th…
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…
The flat tail in the burst energy distribution of FRB 20240114A
Yu-Xiang Huang, Jun-Shuo Zhang, Heng Xu +19
Fast Radio Bursts (FRBs) are enigmatic millisecond-duration radio transients of extra-galactic origin, whose underlying mechanisms and progenitors remain poorly understood. FRBs ar…
Polarization Position Angle Swing and the Rotating Vector Model of Repeating Fast Radio Bursts
Xiaohui Liu, Heng Xu, Jiarui Niu +23
Fast radio bursts (FRBs), typically highly polarized, usually have a nearly constant polarization position angle (PA) during each burst. Some bursts show significant PA variations,…
A Linear Decomposition Method to Analyze and Study Pulsar Mode Changes
Longfei Hao, Zhixuan Li, Faxin Shen +5
In this paper, we present the linear decomposition method (LDM), which we developed to detect and analyze pulsar profile variations and mode changing behaviour. We developed LDM ut…
Chinese Pulsar Timing Array upper limits on microhertz gravitational waves from supermassive black-hole binaries using PSR J1713+0747 FAST data
R. Nicolas Caballero, Heng Xu, Kejia Lee +6
We derive the gravitational-wave (GW) strain upper limits from resolvable supermassive black-hole binaries using the data from the Five-hundred-meter Aperture Spherical radio Teles…
The Chinese pulsar timing array data release I. Polarimetry for 56 millisecond pulsars

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…
Is the Gum Nebula an Important Interstellar Scattering Disk of Background Pulsars?
Rui Wang, Zhen Yan, Zhiqiang Shen +6
The Gum Nebula is a faint supernova remnant extending about 40 degrees across the southern sky, potentially affecting tens of background pulsars. Though the view that the Gum Nebul…
