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…
