Discovery of Two Consecutive Profile Change Events in the Millisecond Pulsar PSR J0437-4715
Rami F. Mandow, Andrew Zic, J. R. Dawson +19
The closest and brightest millisecond pulsar (MSP), PSR J0437-4715, is a high-priority pulsar for precision timing experiments, including the Parkes Pulsar Timing Array (PPTA) proj…
Time-Correlated Profile Variability in the MeerKAT Pulsar Timing Array
Bhavnesh Bhat, Michael J. Keith, E. Carli +2
Long-term pulse-profile variability has emerged as a potentially important source of uncertainty for high-precision pulsar timing, as changes in the integrated pulse shape can bias…
JUG: JAX-based Unified pulsar timinG
Matthew T. Miles, Stephen R. Taylor, Matthew Bailes +14
We present JUG (JAX-based Unified pulsar timinG), a JAX-based, fully independent pulsar timing package emphasising speed and ease of use, designed to confidently handle the increas…
The SKAO Pulsar Timing Array
Ryan M. Shannon, N. D. Ramesh Bhat, Aurélien Chalumeau +22
Pulsar timing arrays (PTAs) are ensembles of millisecond pulsars observed for years to decades. The primary goal of PTAs is to study gravitational-wave astronomy at nanohertz frequ…
The Thousand-Pulsar-Array programme on MeerKAT XIX: Single-pulse data analysis, nulling and pulse energy distributions
Michael J. Keith, Patrick Weltevrede, Lucy Oswald +8
We present the Thousand Pulsar Array (TPA) single-pulse data set, obtained with the MeerKAT radio telescope and comprising time-series observations of 1192 pulsars, typically conta…

Ryan M. Shannon, N. D. Ramesh Bhat, Aurelien Chalumeau +23
Pulsar timing arrays (PTAs) are ensembles of millisecond pulsars observed for years to decades. The primary goal of PTAs is to study gravitational-wave astronomy at nanohertz frequ…
The Thousand-Pulsar-Array programme on MeerKAT -- XVIII. Complex sub-pulse modulation patterns, bi-drifting and mode changing of nine radio pulsars
Haoyue Wang, Michael J. Keith, Patrick Weltevrede +4
We present a detailed analysis of sub-pulse modulations in nine pulsars which show evidence of changes in sub-pulse drift direction as a function of pulse longitude in the Thousand…
Tackling artefacts in the timing of relativistic pulsar binaries: towards the SKA
Huanchen Hu, Nataliya K. Porayko, Willem van Straten +3
Common signal-processing approximations produce artefacts when timing pulsars in relativistic binary systems, especially edge-on systems with tight orbits, such as the Double Pulsa…
The MeerKAT Pulsar Timing Array: Maps of the gravitational-wave sky with the 4.5 year data release
Kathrin Grunthal, Rowina S. Nathan, Eric Thrane +16
In an accompanying publication, the MeerKAT Pulsar Timing Array (MPTA) collaboration reports tentative evidence for the presence of a stochastic gravitational-wave background, foll…
The MeerKAT Pulsar Timing Array: The first search for gravitational waves with the MeerKAT radio telescope
Matthew T. Miles, Ryan M. Shannon, Daniel J. Reardon +22
Pulsar Timing Arrays search for nanohertz-frequency gravitational waves by regularly observing ensembles of millisecond pulsars over many years to look for correlated timing residu…
The MeerKAT Pulsar Timing Array: The -year data release and the noise and stochastic signals of the millisecond pulsar population
Matthew T. Miles, Ryan M. Shannon, Daniel J. Reardon +21
Pulsar timing arrays are ensembles of regularly observed millisecond pulsars timed to high precision. Each pulsar in an array could be affected by a suite of noise processes, most…
The Thousand-Pulsar-Array programme on MeerKAT XIV: On the high linearly polarized pulsar signals
Simon Johnston, Dipanjan Mitra, Michael Keith +2
The S-shaped swing of the linear polarization position angle (PPA) observed in many pulsars can be interpreted by the rotating vector model (RVM). However, efforts to fit the RVM f…
The Thousand-Pulsar-Array programme on MeerKAT XIII: Timing, flux density, rotation measure and dispersion measure timeseries of 597 pulsars
M. J. Keith, S. Johnston, A. Karastergiou +9
We report here on the timing of 597 pulsars over the last four years with the MeerKAT telescope. We provide Times-of-Arrival, pulsar ephemeris files and per-epoch measurements of t…
The Thousand-Pulsar-Array programme on MeerKAT -- XII. Discovery of long-term pulse profile evolution in 7 young pulsars
A. Basu, P. Weltevrede, M. J. Keith +6
A number of pulsars are known to have profile evolution on timescales of months, often correlated with spin-down rate changes. Here, we present the first result from 3 years of mon…

We present the first 2.5 years of data from the MeerKAT Pulsar Timing Array (MPTA), part of MeerTime, a MeerKAT Large Survey Project. The MPTA aims to precisely measure pulse arriv…
The Thousand-Pulsar-Array programme on MeerKAT XI: Application of the rotating vector model
Simon Johnston, Michael Kramer, Aris Karastergiou +4
In spite of the rich phenomenology of the polarization properties of radio pulsars, the rotating vector model (RVM) created 50 years ago remains the best method to determine the be…
