Flux density variability of 286 radio pulsars from a decade of monitoring
H. Kumamoto, S. Dai, S. Johnston +7
The Parkes telescope has been monitoring 286 radio pulsars approximately monthly since 2007 at an observing frequency of 1.4 GHz. The wide dispersion measure (DM) range of the puls…
A single pulse study of PSR J1022+1001
Yi Feng, George Hobbs, Di Li +11
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we have recorded 10^5 single pulses from PSR J1022+1001. We studied the polarization properties, their energ…
Wideband Monitoring Observations of PSR J1803-3002A in the Globular Cluster NGC 6522
Lei Zhang, Richard N. Manchester, Andrew D. Cameron +10
We report the first wideband monitoring observations of PSR J1803-3002A, a relatively bright millisecond pulsar in the globular cluster NGC 6522 with a spin period of 7.1 ms and no…
Identifying and mitigating noise sources in precision pulsar timing data sets
Boris Goncharov, D. J. Reardon, R. M. Shannon +14
Pulsar timing array projects measure the pulse arrival times of millisecond pulsars for the primary purpose of detecting nanohertz-frequency gravitational waves. The measurements i…
On the Circular Polarisation of Repeating Fast Radio Bursts
Shi Dai, Jiguang Lu, Chen Wang +9
Fast spinning (e.g., sub-second) neutron star with ultra-strong magnetic fields (or so-called magnetar) is one of the promising origins of repeating fast radio bursts (FRBs). Here…
A multi-wavelength study of PSR J11196127 after 2016 outburst
H. -H. Wang, L. C. -C. Lin, S. Dai +4
PSR~J11196127, a high-magnetic field pulsar detected from radio to high-energy wavelengths, underwent a magnetar-like outburst beginning on July 27, 2016. In this paper, we stud…
