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…
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…
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…
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…
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…
Investigation of individual pulse emission behaviours from pulsar J17410840
Yonghua Xu, Zhigang Wen, Jianping Yuan +8
We have carried out a detailed study of individual pulse emission from the pulsar J17410840 (B173808), observed using the Parkes and Effelsberg radio telescopes at the ba…
