Turnover in the millisecond pulsar spin noise

In this project, we performed an analysis of millisecond pulsar spin noise using the first data release (DR1) of the International Pulsar Timing Array (IPTA) collaboration. We were particularly interested in determining whether the amplitude of timing residuals, induced by this noise process, keeps growing with longer observations or eventually flattens. We also considered a physical model of millisecond pulsar spin noise, where the noise process is driven by the superfluid turbulence in the core of a neutron star. Our key results:
