Temporal Memory in Repeating Fast Radio Bursts: Epsilon-Machine Reconstruction of Causal Structure in Burst Timing
Tom Kimpson, Joseph O'Leary
The study applies ε‑machine reconstruction to the burst arrival times of repeating fast radio bursts, showing that two repeaters exhibit about one bit of temporal memory while a th…
Narrow spectral artifact investigation and mitigation in LIGO data from the fourth LIGO-Virgo-KAGRA observing run
E. Goetz, A. Neunzert, A. M. Knee +260
We present efforts to identify, characterize, and mitigate narrow spectral artifacts in LIGO detector data during the fourth LIGO-Virgo-KAGRA observing run. Narrow spectral artifac…
Reduced-Precision Stochastic Simulation for Mathematical Biology
Tom Kimpson, Mark B. Flegg, Jennifer A. Flegg
The stochastic simulation algorithm (SSA) is widely used to perform exact forward simulation of discrete stochastic processes in biology. However, the computational cost, driven by…
Search for continuous gravitational waves from neutron stars in five globular clusters in the first part of the fourth LIGO-Virgo-KAGRA observing run
Damon H. T. Cheung, Keith Riles, Rafel Amengual +14
We present the results of directed searches for continuous gravitational waves from unknown neutron stars in five Milky Way globular clusters. We carry out the searches in the LIGO…
Multiscale Modelling of Birth-Death Processes
Tom Kimpson, Domenic P. J. Germano, Jennifer A. Flegg +1
Many biological systems exhibit multiscale dynamics, where some species occur in high copy numbers while others remain rare. This heterogeneity necessitates hybrid modelling approa…
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 multiye…
