The Real and Pseudo Dispersion Measures of FRB~20220912A
Yi Feng, Dengke Zhou, Y. -K. Zhang +5
Fast radio bursts (FRBs) are millisecond-duration radio transients. As they propagate through the interstellar medium, they interact with free electrons, resulting in dispersion. T…
Revealing the Temporally Stable Bimodal Energy Distribution of FRB 20121102A with a Tripled Burst Set from AI Detections
Yidan Wang, Jing Han, Pei Wang +34
Active repeating Fast Radio Bursts (FRBs), with their large number of bursts, burst energy distribution, and their potential energy evolution, offer critical insights into the FRBs…
Accelerating FRB Search: Dataset and Methods
Xuerong Guo, Han Wang, Yifan Xiao +11
Fast Radio Burst (FRB) is an extremely energetic cosmic phenomenon of short duration. Discovered only recently and with its origin still unknown, FRBs have already started to play…
Refined Constraints on the Hubble Constant from Localized FRBs with Assessment of Systematic Effects
Chenyuan Xu, Yi Feng, Jiaying Xu
The dispersion measure-redshift relation of fast radio bursts (FRBs) provides a valuable cosmological probe for constraining the Hubble constant, offering an independent measuremen…
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…
Polarization Characteristics of the Hyperactive FRB 20240114A
Jin-Tao Xie, Yi Feng, Di Li +14
Fast radio bursts (FRBs) are transient radio bursts of extragalactic origin characterized by millisecond durations and high luminosities. We report on observations of FRB 20240114A…
