Probing Neutron Star Interiors and the Properties of Cold Ultra-dense Matter with the SKAO
Avishek Basu, Vanessa Graber, Marcus E. Lower +19
Matter inside neutron stars is compressed to densities several times greater than nuclear saturation density, while maintaining low temperatures and large asymmetries between neutr…

PSR J0537-6910: Exponential recoveries detected for 12 glitches
E. Zubieta, C. M. Espinoza, D. Antonopoulou +4
Pulsar glitches are unresolved increments of the rotation rate that sometimes trigger an enhancement of the spin-down rate. On occasions, the augmented spin-down decays gradually i…
Braking index of the frequently glitching PSR J05376910
Erbil Gügercinoğlu, Onur Akbal, M. Ali Alpar +2
The pulsar J05376910 undergoes spin-up glitches more frequently than any other known pulsar, at a rate of roughly thrice per year. Its glitches are typically large and accompani…
Signatures of magnetic flux expulsion from neutron star cores
S. K. Lander, K. N. Gourgouliatos, Z. Wadiasingh +1
Shortly after a neutron star is born, the protons in its core begin to form a superconductor. In terrestrial materials, the hallmark of superconductivity is an associated expulsion…
A growing braking index and spin-down swings for the pulsar PSR B0540-69
Cristóbal M. Espinoza, Lucien Kuiper, Wynn C. G. Ho +5
The way pulsars spin down is not understood in detail, but a number of possible physical mechanisms produce a spin-down rate that scales as a power of the rotation rate ($\dotν\pro…
The TRAPUM Small Magellanic Cloud pulsar survey with MeerKAT -- II. Nine new radio timing solutions and glitches from young pulsars
E. Carli, D. Antonopoulou, M. Burgay +17
We report new radio timing solutions from a three-year observing campaign conducted with the MeerKAT and Murriyang telescopes for nine Small Magellanic Cloud pulsars, increasing th…
A new small glitch in Vela discovered with a hidden Markov model
L. Dunn, A. Melatos, C. M. Espinoza +2
A striking feature of the Vela pulsar (PSR J08354510) is that it undergoes sudden increases in its spin frequency, known as glitches, with a fractional amplitude on the order of…
Timing six energetic rotation-powered X-ray pulsars, including the fast-spinning young PSR J0058-7218 and Big Glitcher PSR J0537-6910
Wynn C. G. Ho, Lucien Kuiper, Cristobal M. Espinoza +14
Measuring a pulsar's rotational evolution is crucial to understanding the nature of the pulsar. Here we provide updated timing models for the rotational evolution of six pulsars, f…
The Jodrell Bank Glitch Catalogue: 106 new rotational glitches in 70 pulsars
Avishek Basu, Benjamin Shaw, Danai Antonopoulou +6
Pulsar glitches are rapid spin-up events that occur in the rotation of neutron stars, providing a valuable probe into the physics of the interiors of these objects. Long-term monit…
Return of the Big Glitcher: NICER timing and glitches of PSR J0537-6910
Wynn C. G. Ho, Cristobal M. Espinoza, Zaven Arzoumanian +7
PSR J0537-6910, also known as the Big Glitcher, is the most prolific glitching pulsar known, and its spin-induced pulsations are only detectable in X-ray. We present results from a…
Turbulent, pinned superfluids in neutron stars and pulsar glitch recoveries
Brynmor Haskell, Danai Antonopoulou, Carlo Barenghi
Pulsar glitches offer an insight into the dynamics of superfluids in the high density interior of a neutron star. To model these phenomena, however, one needs to have an understand…
Small glitches and other rotational irregularities of the Vela pulsar
C. M. Espinoza, D. Antonopoulou, R. Dodson +2
Glitches are sudden increases in the rotation rate of neutron stars, which are thought to be driven by the neutron superfluid inside the star. The Vela pulsar presents a compar…
Core and crust contributions in pulsar glitches: constraints from the slow rise of the largest glitch observed in the Crab pulsar
Brynmor Haskell, Vadym Khomenko, Marco Antonelli +1
Pulsar glitches are attributed to the sudden re-coupling of very weakly coupled large scale superfluid components in the neutron star interior. This process leads to rapid exchange…
The enigmatic spin evolution of PSR J0537-6910: r-modes, gravitational waves and the case for continued timing
N. Andersson, D. Antonopoulou, C. M. Espinoza +2
We discuss the unique spin evolution of the young X-ray pulsar PSR J0537-6910, a system in which the regular spin down is interrupted by glitches every few months. Drawing on the c…
Pulsar spin-down: the glitch-dominated rotation of PSR J0537-6910
D. Antonopoulou, C. M. Espinoza, L. Kuiper +1
The young, fast-spinning, X-ray pulsar J0537-6910 displays an extreme glitch activity, with large spin-ups interrupting its decelerating rotation every ~100 days. We present nearly…
Pinning down the superfluid and nuclear equation of state and measuring neutron star mass using pulsar glitches

Magnetically-driven crustquakes in neutron stars
