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,…

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 Chinese pulsar timing array data release I. Polarimetry for 56 millisecond pulsars

Jiangwei Xu, Jinchen Jiang, Heng Xu +27

We present polarization pulse profiles for 56 millisecond pulsars (MSPs) monitored by the Chinese Pulsar Timing Array (CPTA) collaboration using the Five-hundred-meter Aperture Sph…

Ninety percent circular polarization detected in a repeating fast radio burst

J. C. Jiang, J. W. Xu, J. R. Niu +34

Fast radio bursts (FRBs) are extra-galactic sources with unknown physical mechanisms. They emit millisecond-duration radio pulses with isotropic equivalent energy of $10^{36}\sim10…
