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…
Supernova Classification using the Recurrent Neural Network in the CSST Ultra-Deep Field Survey
Minglin Wang, Yan Gong, Dejia Zhou +1
We study supernova (SN) classification using the Recurrent Neural Networks (RNNs) within the Chinese Space-station Survey Telescope Ultra-Deep Field (CSST-UDF) photometric survey a…
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…
Towards DM-free search for Fast Radio Bursts with Machine Learning -- I. An implementation on multibeam data
Yao Chen, Rui Luo, Chen Wang +13
Searching for fleeting radio transients like fast radio bursts (FRBs) with wide-field radio telescopes has become a common challenge in data-intensive science. Conventional algorit…
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 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,…
