Understanding Pulsar Magnetospheres with the SKAO
L. S. Oswald, A. Basu, M. Chakraborty +21
The SKA telescopes will bring unparalleled sensitivity across a broad radio band, a wide field of view across the Southern sky, and the capacity for sub-arraying, all of which make…
Understanding pulsar magnetospheres with the SKAO
L. S. Oswald, A. Basu, M. Chakraborty +22

Main and interpulse interaction in PSRs J1842+0358 and J1926+0737: evidence for interpole communication
X. Song, P. Weltevrede, J. van Leeuwen +2
Our understanding of the elusive radio-pulsar emission mechanism would be deepened by determining the locality of the emission. Pulsars in which the two poles interact can potentia…
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…
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…
The Thousand-Pulsar-Array programme on MeerKAT -- VIII. The subpulse modulation of 1198 pulsars
X. Song, P. Weltevrede, A. Szary +13
We report on the subpulse modulation properties of 1198 pulsars using the Thousand-Pulsar-Array programme on MeerKAT. About 35% of the analysed pulsars exhibit drifting subpulses w…
The Thousand-Pulsar-Array program on MeerKAT -- IX. The time-averaged properties of the observed pulsar population
B. Posselt, A. Karastergiou, S. Johnston +14
We present the largest single survey to date of average profiles of radio pulsars, observed and processed using the same telescope and data reduction software. Specifically, we pre…
The Thousand-Pulsar-Array programme on MeerKAT -- X. Scintillation arcs of 107 pulsars
R. A. Main, A. Parthasarathy, S. Johnston +9
We present the detection of 107 pulsars with interstellar scintillation arcs at 856--1712\,MHz, observed with the MeerKAT Thousand Pulsar Array Programme. Scintillation arcs appear…
The Thousand-Pulsar-Array programme on MeerKAT: -- VI. Pulse widths of a large and diverse sample of radio pulsars
B. Posselt, A. Karastergiou, S. Johnston +14
We present pulse width measurements for a sample of radio pulsars observed with the MeerKAT telescope as part of the Thousand-Pulsar-Array (TPA) programme in the MeerTime project.…
The Thousand-Pulsar-Array programme on MeerKAT II: observing strategy for pulsar monitoring with subarrays
X. Song, P. Weltevrede, M. J. Keith +15
The Thousand Pulsar Array (TPA) project currently monitors about 500 pulsars with the sensitive MeerKAT radio telescope by using subarrays to observe multiple sources simultaneousl…
A New Transient Ultraluminous X-ray Source in NGC 7090
D. J. Walton, M. Heida, M. Bachetti +17
We report on the discovery of a new, transient ultraluminous X-ray source (ULX) in the galaxy NGC 7090. This new ULX, which we refer to as NGC 7090 ULX3, was discovered via monitor…
The Thousand-Pulsar-Array programme on MeerKAT I: Science objectives and first results
Simon Johnston, A. Karastergiou, M. J. Keith +24
We report here on initial results from the Thousand Pulsar Array (TPA) programme, part of the Large Survey Project "MeerTime" on the MeerKAT telescope. The interferometer is used i…
The Hunt for Pulsating Ultraluminous X-ray Sources
X. Song, D. J. Walton, G. B. Lansbury +4
Motivated by the recent discoveries that six Ultraluminous X-ray Sources (ULXs) are powered by highly super-Eddington X-ray pulsars, we searched for additional pulsating ULX (PULX)…
