Discovering pulsars in compact binaries with a hidden Markov model

Joseph O'Leary, Liam Dunn, Andrew Melatos

Discovering radio pulsars in compact binaries, whose orbital periods satisfy , is computationally challenging, because the time-depend…

Is there a retrograde accretion disk around 4U 162667? Tracking torque reversals with a state-space model

Joseph O'Leary, Andrew Melatos, Tom Kimpson +5

X-ray timing studies of the persistent, Galactic, accretion-powered pulsar 4U 162667 reveal torque reversals, during which the pulse frequency alternates between multiyea…

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…

Kalman tracking and parameter estimation of continuous gravitational waves with a pulsar timing array

Tom Kimpson, Andrew Melatos, Joseph O'Leary +11

Continuous nanohertz gravitational waves from individual supermassive black hole binaries may be detectable with pulsar timing arrays. A novel search strategy is developed, wherein…
