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…
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…
The SKAO Pulsar Timing Array
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…
