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…
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…
Estimating and detecting random processes on the unit circle
Changrong Liu, S. Suvorova, R. J. Evans +2
The problem of detecting a sinusoidal signal with randomly varying frequency has a long history. It is one of the core problems in signal processing, arising in many applications i…
Bayesian Detection of a Sinusoidal Signal with Randomly Varying Frequency
Changrong Liu, S. Suvorova, R. J. Evans +2
The problem of detecting a sinusoidal signal with randomly varying frequency has a long history. It is one of the core problems in signal processing, arising in many applications i…
Systematic upper limits on the size of missing pulsar glitches in the first UTMOST open data release
L. Dunn, A. Melatos, S. Suvorova +7
A systematic, semi-automated search for pulsar glitches in the first UTMOST public data release is presented. The search is carried out using a hidden Markov model which incorporat…
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…
Neutron Star Extreme Matter Observatory: A kilohertz-band gravitational-wave detector in the global network
K. Ackley, V. B. Adya, P. Agrawal +160
Gravitational waves from coalescing neutron stars encode information about nuclear matter at extreme densities, inaccessible by laboratory experiments. The late inspiral is influen…
Pulsar glitch detection with a hidden Markov model
A. Melatos, L. M. Dunn, S. Suvorova +2
Pulsar timing experiments typically generate a phase-connected timing solution from a sequence of times-of-arrival (TOAs) by absolute pulse numbering, i.e. by fitting an integer nu…
Bayesian Recursive Estimation on the Rotation Group
Sofia Suvorova, Stephen D. Howard, Bill Moran
Tracking on the rotation group is a key component of many modern systems for estimation of the motion of rigid bodies. To address this problem, here we describe a Bayesian algorith…
Reconstructing Gravitational Wave Core-Collapse Supernova Signals with Dynamic Time Warping
Sofia Suvorova, Jade Powell, Andrew Melatos
Core-collapse supernovae (CCSNe) are a potential source for ground-based gravitational wave detectors, as their predicted emission peaks in the detectors' frequency band. Typical s…
Controlled Tracking in Urban Terrain: Closing the Loop
Patricia R. Barbosa, Yugandhar Sarkale, Edwin K. P. Chong +3
We investigate the challenging problem of integrating detection, signal processing, target tracking, and adaptive waveform scheduling with lookahead in urban terrain. We propose a…
Hidden Markov model tracking of continuous gravitational waves from young supernova remnants
L. Sun, A. Melatos, S. Suvorova +2
Searches for persistent gravitational radiation from nonpulsating neutron stars in young supernova remnants (SNRs) are computationally challenging because of rapid stellar braking.…
Hidden Markov model tracking of continuous gravitational waves from a neutron star with wandering spin
S. Suvorova, L. Sun, A. Melatos +2
Gravitational wave searches for continuous-wave signals from neutron stars are especially challenging when the star's spin frequency is unknown a priori from electromagnetic observ…
Bounds on Multiple Sensor Fusion
Bill Moran, Fred Cohen, Zengfu Wang +5
We consider the problem of fusing measurements from multiple sensors, where the sensing regions overlap and data are non-negative---possibly resulting from a count of indistinguish…
