Generalized Non-linear Bayesian Pulsar Timing with Enterprise
Andrew R. Kaiser, Jeffrey S. Hazboun, Maura A. McLaughlin +56
In this study, we use the Bayesian methods in the Enterprise package to examine the fully general parameterization of pulsar timing models in tandem with noise. We investigate four…
A joint MeerKAT and Parkes view of Omega Centauri: New TRAPUM Searches and Pulsar Timing
Miquel Colom i Bernadich, Shi Dai, Federico Abbate +27
Millisecond pulsars (MSPs) are powerful probes of globular clusters (GCs), tracing stellar evolution, cluster dynamics, and the local gravitational potential. We investigate the MS…
Ultra-Wideband Polarimetry of the April 2021 Profile Change Event in PSR J1713+0747
Rami F. Mandow, Andrew Zic, J. R. Dawson +15
The millisecond pulsar PSR J1713+0747 is a high-priority target for pulsar timing array experiments due to its long-term timing stability, and bright, narrow pulse profile. In Apri…
The neutron star mass, distance, and inclination from precision timing of the brilliant millisecond pulsar J04374715
Daniel J. Reardon, Matthew Bailes, Ryan M. Shannon +17
The observation of neutron stars enables the otherwise impossible study of fundamental physical processes. The timing of binary radio pulsars is particularly powerful, as it enable…
Cannonball or Bowling Ball: A Proper Motion and Parallax for PSR J0002+6216

We report the results of careful astrometric measurements of the Cannonball pulsar J0002+6216 carried out over three years using the High Sensitivity Array (HSA). We significantly…
The impact of glitches on young pulsar rotational evolution
Marcus E. Lower, Simon Johnston, Liam Dunn +10
We report on a timing programme of 74 young pulsars that have been observed by the Parkes 64-m radio telescope over the past decade. Using modern Bayesian timing techniques, we hav…
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…
Extremely band-limited repetition from a fast radio burst source
Pravir Kumar, Ryan M. Shannon, Chris Flynn +11
The fast radio burst (FRB) population is observationally divided into sources that have been observed to repeat and those that have not. There is tentative evidence that the bursts…
Timing of young radio pulsars II. Braking indices and their interpretation
A. Parthasarathy, S. Johnston, R. M. Shannon +8
In Paper I of this series, we detected a significant value of the braking index () for 19 young, high- radio pulsars using 10 years of timing observations from t…
The International Pulsar Timing Array: Second data release
B. B. P. Perera, M. E. DeCesar, P. B. Demorest +72
In this paper, we describe the International Pulsar Timing Array second data release, which includes recent pulsar timing data obtained by three regional consortia: the European Pu…
Timing of young radio pulsars I: Timing noise, periodic modulation and proper motion
A. Parthasarathy, R. M. Shannon, S. Johnston +9
The smooth spin-down of young pulsars is perturbed by two non-deterministic phenomenon, glitches and timing noise. Although the timing noise provides insights into nuclear and plas…
Commensal discovery of four Fast Radio Bursts during Parkes Pulsar Timing Array observations
S. Osłowski, R. M. Shannon, V. Ravi +25
The Parkes Pulsar Timing Array (PPTA) project monitors two dozen millisecond pulsars (MSPs) in order to undertake a variety of fundamental physics experiments using the Parkes 64m…
The Tail of PSR J0002+6216 and the Supernova Remnant CTB 1
