The impact of glitches on young pulsar rotational evolution
Marcus E. Lower, Simon Johnston, Liam Dunn +10
We report on a timing programme of 74 young pulsars that have been observed by the Parkes 64-m radio telescope over the past decade. Using modern Bayesian timing techniques, we hav…
Hidden Markov model tracking of continuous gravitational waves from a neutron star with wandering spin. III. Rotational phase tracking
A. Melatos, P. Clearwater, S. Suvorova +3
A hidden Markov model (HMM) solved recursively by the Viterbi algorithm can be configured to search for persistent, quasimonochromatic gravitational radiation from an isolated or a…
Long-term statistics of pulsar glitches due to history-dependent avalanches
Julian B. Carlin, Andrew Melatos
Stress accumulation-relaxation meta-models of pulsar glitches make precise, microphysics-agnostic predictions of long-term glitch statistics, which can be falsified by existing and…
Effects of periodicity in observation scheduling on parameter estimation of pulsar glitches
Liam Dunn, Marcus E. Lower, Andrew Melatos
In certain pulsar timing experiments, where observations are scheduled approximately periodically (e.g. daily), timing models with significantly different frequencies (including bu…
Deep exploration for continuous gravitational waves at 171--172 Hz in LIGO second observing run data
Karl Wette, Liam Dunn, Patrick Clearwater +1
We pursue a novel strategy towards a first detection of continuous gravitational waves from rapidly-rotating deformed neutron stars. Computational power is focused on a narrow regi…
Testing for a Random Walk Structure in the Frequency Evolution of a Tone in Noise
S. E. Abramson, W. Moran, R. J. Evans +1
Inference and hypothesis testing are typically constructed on the basis that a specific model holds for the data. To determine the veracity of conclusions drawn from such data anal…
