# Generating quasiperiodic pulsar glitches using a state-dependent Poisson process

## TL;DR

This paper demonstrates that a modified state-dependent Poisson process can replicate both Poisson-like and unimodal pulsar glitch behaviors by adjusting a single parameter, offering insights into pulsar microphysics.

## Contribution

It introduces a modification to the existing Poisson process model that can generate both classes of pulsar glitch statistics with a single control parameter.

## Key findings

- The model reproduces Poisson-like waiting times and sizes.
- Adjusting the control parameter yields unimodal distributions.
- Implications for understanding pulsar glitch mechanisms.

## Abstract

Glitching pulsars fall broadly into two statistical classes: those with Poisson-like waiting times and power-law sizes, and those with unimodal waiting times and sizes. Previous glitch modeling based on a state-dependent Poisson process readily generates Poisson-like behaviour but struggles to produce unimodal waiting times or sizes. Here it is shown that, when some of the inputs to the model are modified, both classes of statistical behaviour can be reproduced by varying a single control parameter related to the spin-down rate. The implications for past and future glitch observations and the underlying microphysical mechanism are explored briefly.
