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…
Frequency evolution of pulsar emission: Further evidence for fan beam model
P. Jaroenjittichai, S. Johnston, S. Dai +7
Aims. We explore frequency-dependent changes in pulsar radio emission by analyzing their profile widths and emission heights, assessing whether the simple radius-to-frequency mappi…
The Thousand-Pulsar-Array programme on MeerKAT -- XVI. Mapping the Galactic magnetic field with pulsar observations
L. S. Oswald, P. Weltevrede, B. Posselt +3
Measuring the magnetic field of the Milky Way reveals the structure and evolution of the galaxy. Pulsar rotation measures (RMs) provide a means to probe this Galactic magnetic fiel…
The ubiquity of variable radio emission and spin-down rates in pulsars
M. E. Lower, A. Karastergiou, S. Johnston +8
Pulsars are often lauded for their (relative) rotational and radio emission stability over long time scales. However, long-term observing programmes are identifying an increasing n…
The Thousand-Pulsar-Array programme on MeerKAT XVII: Discovery of beating radio emission variability in PSR J1514-4834
J. A. Hsu, P. Weltevrede, G. Wright +4
We present a comprehensive analysis of the complex subpulse modulation patterns in PSR J1514-4834 (B1510-48) using L-band data from the Thousand-Pulsar-Array (TPA) programme, compl…
