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…

State-space analysis of a continuous gravitational wave source with a pulsar timing array: inclusion of the pulsar terms
Tom Kimpson, Andrew Melatos, Joseph O'Leary +11
Pulsar timing arrays can detect continuous nanohertz gravitational waves emitted by individual supermassive black hole binaries. The data analysis procedure can be formulated withi…
