Measuring the crust-superfluid coupling time-scale for 105 UTMOST pulsars with a Kalman filter
Wenhao Dong, Andrew Melatos, Nicholas J. O'Neill +2
Crust-superfluid coupling plays an important role in neutron star rotation, particularly with respect to timing noise and glitches. Here, we present new timing-noise-based estimate…

State-space algorithm for detecting the nanohertz gravitational wave background
Tom Kimpson, Andrew Melatos, Joseph O'Leary +11
The stochastic gravitational wave background (SGWB) can be observed in the nanohertz band using a pulsar timing array (PTA). Here a computationally efficient state-space framework…

Gravitational waves from r-mode oscillations of stochastically accreting neutron stars
Wenhao Dong, Andrew Melatos
-mode oscillations in rotating neutron stars are a source of continuous gravitational radiation. We investigate the excitation of -modes by the mechanical impact on the neutr…
