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…

Discovery and Timing of Four -ray Millisecond Pulsars

M. Kerr, S. Johnston, C. J. Clark +11

We discovered four millisecond pulsars (MSPs) in searches of 80 -ray sources conducted from 2015 to 2017 with the Murriyang radio telescope of the Parkes Observatory. We provide…

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…
