A pulsar-helium star compact binary system formed by common envelope evolution
Z. L. Yang, J. L. Han, D. J. Zhou +33
A stellar common envelope occurs in a binary system when the atmosphere of an evolving star expands to encompass an orbiting companion object. Such systems are predicted to evolve…
Modelling The Radial Distribution of Pulsars in the Galaxy
J. T. Xie, J. B. Wang, N. Wang +2
The Parkes 20 cm Multibeam pulsar surveys have discovered nearly half of the known pulsars and revealed many distant pulsars with high dispersion measures. Using a sample of 1,301…
Pulse Jitter and Single-pulse Variability in Millisecond Pulsars
S. Q. Wang, N. Wang, J. B. Wang +8
Understanding the jitter noise resulting from single-pulse phase and shape variations is important for the detection of gravitational waves using pulsar timing array. We presented…
Discovery of four pulsars in a pilot survey at intermediate Galactic latitudes with FAST
Q. J. Zhi, J. T. Bai, S. Dai +21
We present the discovery and timing results of four pulsars discovered in a pilot survey at intermediate Galactic latitudes with the Five-hundred Aperture Spherical Telescope (FAST…
Unusual Emission Variations Near the Eclipse of A Black Widow PSR J17200533
S. Q. Wang, J. B. Wang, N. Wang +15
We report on an {unusually} bright observation of PSR J17200533 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The pulsar is in a black widow system tha…
The Parkes pulsar timing array second data release: Timing analysis
D. J. Reardon, R. M. Shannon, A. D. Cameron +14
The main goal of pulsar timing array experiments is to detect correlated signals such as nanohertz-frequency gravitational waves. Pulsar timing data collected in dense monitoring c…
A single pulse study of a millisecond pulsar PSR J0621+1002
S. Q. Wang, J. B. Wang, N. Wang +8
We present radio observation of a millisecond pulsar PSR J0621+1002 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The pulsar shows periodic pulse intensit…
Searching for gravitational wave bursts from cosmic string cusps with the Parkes Pulsar Timing Array
N. Yonemaru, S. Kuroyanagi, G. Hobbs +12
Cosmic strings are potential gravitational wave (GW) sources that can be probed by pulsar timing arrays (PTAs). In this work we develop a detection algorithm for a GW burst from a…
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…
Comparison of Pulsar Positions from Timing and Very Long Baseline Astrometry
J. B. Wang, W. A. Coles, G. Hobbs +22
Pulsar positions can be measured with high precision using both pulsar timing methods and very-long-baseline interferometry (VLBI). Pulsar timing positions are referenced to a sola…
Pulse profiles and timing of PSR J17572421
J. P. Yuan, R. N. Manchester, N. Wang +4
Pulse arrival time measurements over fourteen years with the Nanshan 25-m and Parkes 64-m radio telescopes have been used to determine the average profile and timing properties for…
Proper motions of 15 pulsars: a comparison between Bayesian and frequentist algorithms
L. Li, N. Wang, J. P. Yuan +4
We present proper motions for 15 pulsars which are observed regularly by the Nanshan 25-m radio telescope. Two methods, the frequentist method (Coles et al.2011) and the Bayesian (…

We present results of an all-sky search in the Parkes Pulsar Timing Array (PPTA) Data Release 1 data set for continuous gravitational waves (GWs) in the frequency range from $5\tim…
Limitations in timing precision due to single-pulse shape variability in millisecond pulsars
R. M. Shannon, S. Osłowski, S. Dai +17
High-sensitivity radio-frequency observations of millisecond pulsars usually show stochastic, broadband, pulse-shape variations intrinsic to the pulsar emission process. These vari…
