The Thousand-Pulsar-Array programme on MeerKAT - XX. Co-existing interacting periodicities and polarization modulation in PSR J1901-0906
Jui-An Hsu, Patrick Weltevrede, Geoff Wright +3
We present a comprehensive analysis of the complex subpulse modulation in PSR J1901-0906 using data from the Thousand-Pulsar-Array (TPA) programme. Our analysis reveals the coexist…
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 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…
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…
