## TL;DR

This paper investigates whether long- and short-term emission variability in pulsars share the same physical origins by proposing a new monitoring technique and exploring its effectiveness through simulations.

## Contribution

It introduces a continuous pulsar monitoring method to detect rotational changes associated with emission variability on short timescales, which was previously unmeasurable.

## Key findings

- Proposes a statistical detection technique for pulsar rotational changes.
- Simulations identify pulsar properties suitable for this monitoring approach.

## Abstract

It is now known that the emission from radio pulsars can vary over a wide range of timescales, from fractions of seconds to decades. However, it is not yet known if long- and short-term emission variability are caused by the same physical processes. It has been observed that long-term emission variability is often correlated with rotational changes in the pulsar. We do not yet know if the same is true of short-term emission variability, as the rotational changes involved cannot be directly measured over such short timescales. To remedy this, we propose a continuous pulsar monitoring technique that permits the statistical detection of any rotational changes in nulling and mode-changing pulsars with certain properties. Using a simulation, we explore the range of pulsar properties over which such an experiment would be possible.
