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…
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…
Chinese Pulsar Timing Array upper limits on microhertz gravitational waves from supermassive black-hole binaries using PSR J1713+0747 FAST data
R. Nicolas Caballero, Heng Xu, Kejia Lee +6
We derive the gravitational-wave (GW) strain upper limits from resolvable supermassive black-hole binaries using the data from the Five-hundred-meter Aperture Spherical radio Teles…
