Testing the Isotropy of the Universe with the CHIME/FRB Catalog I
Jun-Yi Shen, Yuan-Chuan Zou
We test the isotropy of the Universe using 536 Fast Radio Bursts (FRBs) from the first CHIME/FRB catalog, employing two complementary statistical methods: the two-point angular cor…

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…
