The radiative subpulse modulation and spectral features of PSR B192910 with the whole pulse phase emission

Zhengli Wang, Jiguang Lu, Weiyang Wang +7

In this work, we observe the nearby pulsar, PSR B192910, using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We find, for the first time, two new emission co…

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…

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,…

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…

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…

PSR B0943+10: Mode Switch, Polar Cap Geometry, and Orthogonally Polarized Radiation

Shunshun Cao, Jinchen Jiang, Jaroslaw Dyks +10

As one of the paradigm examples to probe into pulsar magnetospheric dynamics, PSR B0943+10 (J0946+0951) manifests representatively, showing mode switch, orthogonal polarization and…

A radio pulsar phase from SGR J1935+2154 provides clues to the magnetar FRB mechanism

Weiwei Zhu, Heng Xu, Dejiang Zhou +34

The megajansky radio burst, FRB 20200428, and other bright radio bursts detected from the Galactic source SGR J1935+2154 suggest that magnetars can make fast radio bursts (FRBs), b…

Searching for the nano-Hertz stochastic gravitational wave background with the Chinese Pulsar Timing Array Data Release I

Heng Xu, Siyuan Chen, Yanjun Guo +24

Observing and timing a group of millisecond pulsars (MSPs) with high rotational stability enables the direct detection of gravitational waves (GWs). The GW signals can be identifie…
