Scintillating insights into PSR~J07373039A and the interstellar plasma of the Gum Nebula from MeerKAT
J. Askew, D. J. Reardon, R. M. Shannon +8
The double pulsar system PSR~J07373039A/B has enabled some of the most precise tests of strong-field gravity to date. Here, we present a scintillation analysis of the system bas…
Measuring scattering variations in pulsar timing observations: A test of the fidelity of current methods
A. D. Kulkarni, R. M. Shannon, D. J. Reardon +1
The turbulent nature of the ionised interstellar medium (IISM) causes dispersion measure (DM) and scattering variations in pulsar timing measurements. To improve precision of gravi…
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 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…
Timing and noise analysis of five millisecond pulsars observed with MeerKAT
M. Chisabi, S. Andrianomena, U. Enwelum +12
Millisecond pulsars (MSPs) in binary systems are precise laboratories for tests of gravity and the physics of dense matter. Their orbits can show relativistic effects that provide…
The High Time Resolution Universe Pulsar Survey-XIX. A coherent GPU accelerated reprocessing and the discovery of 71 pulsars in the Southern Galactic plane
R. Sengar, M. Bailes, V. Balakrishnan +19
We have conducted a GPU accelerated reprocessing of of the archival data from the High Time Resolution Universe South Low Latitude (HTRU-S LowLat) pulsar survey by impl…
