Searches for transient radio sources, independent of any multiwavelength trigger, have traditionally been hindered by a combination of sensitivity and field-of-view. However this has changed with the advent of the Square Kilometre Array (SKA) Pathfinders – the Murchison Widefield Array (MWA; Tingay et al. 2013; Wayth et al. 2018), the Low Frequency Array (van Haarlem et al. 2013), MeerKAT (Jonas & MeerKAT Team 2016), and the Australian SKA Pathfinder (ASKAP; Hotan et al. 2021).

A key tool in the interpretation of the population of radio-emitting neutron stars is the diagram, where the rotational period P is plotted against its first time derivative ⁠. The rationale has always been that, assuming pulsars spin down due to the fact that they are rotating misaligned magnetic dipoles, one can easily draw on these diagrams lines of constant surface magnetic field and lines of constant characteristic age ⁠.

1 Introduction The Phillips curve in various formulations underpins many macroeconomic models and is often used by policymakers as a framework for possible trade-offs between inflation and unemployment. However, the instability over time in such Phillips curves is well known and well documented by both academics and policymakers: see Del Negro et al.

We present a comprehensive study of the rotational and emission properties of PSR J0738−4042 using a combination of observations taken by the Deep Space Network, Hartebeesthoek, Parkes (Murriyang) and Molonglo observatories between 1972 and 2023. Our timing of the pulsar is motivated by previously reported profile/spin-down events that occurred in 2005 September and 2015 December, which result in an anomalously large braking index of n = 23 300 ± 1800.
