Search for continuous gravitational waves from neutron stars in five globular clusters with a phase-tracking hidden Markov model in the third LIGO observing run
L. Dunn, A. Melatos, P. Clearwater +4
A search is performed for continuous gravitational waves emitted by unknown neutron stars in five nearby globular clusters using data from the third Laser Interferometer Gravitatio…

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…

Adaptive cancellation of mains power interference in continuous gravitational wave searches with a hidden Markov model
Tom Kimpson, Sofia Suvorova, Hannah Middleton +4
Continuous gravitational wave searches with terrestrial, long-baseline interferometers are hampered by long-lived, narrowband features in the power spectral density of the detector…
