The interpretation of pulsar rotational glitches, the sudden increase in spin frequency of
neutron stars, is a half-century-old challenge. The common view is that glitches are driven by …

While pulsars possess exceptional rotational stability, large-scale timing studies have
revealed at least two distinct types of irregularities in their rotation: red timing noise and …

The frequency dependence of radio pulse arrival times provides a probe of structures in the
intervening media. Demorest et al. was the first to show a short-term (∼ 100–200 days) …

We study pinning and unpinning of superfluid vortices in the inner crust of a neutron star
using three-dimensional dynamical simulations. Strong pinning occurs for certain lattice …

We report here on the first results of a systematic monitoring of southern glitching pulsars at
the Argentine Institute of Radioastronomy that started in the year 2019. We detected a major …

Few statistically compelling correlations are found in pulsar timing data between the size of
a rotational glitch and the time to the preceding glitch (backward waiting time) or the …

The cores of pulsars are expected to become superconducting soon after birth. The
transition to type-II superconductivity is associated with the bunching of magnetic field lines …

Context. Glitches are sudden increases in the rotation rate ν of neutron stars, which are
thought to be driven by the neutron superfluid inside the star. The Vela pulsar presents a …

Pulsar timing experiments typically generate a phase-connected timing solution from a
sequence of times of arrival (TOAs) by absolute pulse numbering, ie, by fitting an integer …

We reported the first glitch of PSR B2021+ 51 detected with the Shanghai Tian Ma Radio
Telescope that occurred around MJD 58289.1 (2018 June 20). The spin frequency and its …
