Article
A Glitch in the Millisecond Pulsar J0613-0200 is a preprint published by arXiv in 2016. It focuses on timing analysis of millisecond pulsar J0613-0200 achieving microsecond-level precision over 13.7 years, used in gravitational-wave pulsar timing array experiments, with a detected spin glitch event.
Timing precision: 1.2 microseconds over 13.7 years. It also considers part of International Pulsar Timing Array (IPTA) dataset. It also considers millisecond-scale spin period. This gives the cycle claim a specific numerical and evidential setting rather than presenting periodicity only as a visual impression.
The article reports the following result: Pulsars spin with remarkable stability, allowing pulse times of arrival to be accurately predicted with precisions as high as fractions of microseconds over timescales of decades; PSR J0613-0200 has been timed to a precision of 1.2 microseconds over 13.7 years. The interpretation is strongest when it survives red-noise modelling, uneven sampling, spectral-window effects and correction for the number of frequencies searched.
For cycles researchers, the article brings together millisecond pulsar, pulsar glitch, timing arrays, gravitational waves. It is relevant to the detection and interpretation of periodic signals in astronomical observations, where sampling, red noise and instrumental effects can imitate or obscure genuine cycles.
Because it is a preprint, the work should be read alongside later peer-reviewed publications and independent replications. It remains useful because the proposed cycle, dataset and analytical approach are stated clearly enough to be scrutinised.
