Time-Correlated Profile Variability in the MeerKAT Pulsar Timing Array

Abstract Long-term pulse-profile variability has emerged as a potentially important source of uncertainty for high-precision pulsar timing, as changes in the integrated pulse shape can bias pulse times of arrival and affect the sensitivity of pulsar timing arrays to nanohertz gra...

From mass-loss histories to lightcurves: a generalised framework for interaction-powered transients

Abstract We introduce a fast (~1–50 ms) and generalised public framework for modelling interaction-powered transients. The framework solves the thin-shell equations of motion for ejecta colliding with circumstellar material (CSM), and supports arbitrary CSM density and velocity p...
