Detectability of microlensed gravitational waves
Simon M. C. Yeung, Mark H. Y. Cheung, Joseph A. J. Gais +2
Gravitational lensing describes the bending of the trajectories of light and gravitational waves due to the gravitational potential of a massive object. Strong lensing by galaxies…
Testing the robustness of simulation-based gravitational-wave population inference
Damon H. T. Cheung, Kaze W. K. Wong, Otto A. Hannuksela +2
Gravitational-wave population studies have become more important in gravitational-wave astronomy because of the rapid growth of the observed catalog. In recent studies, emulators b…
Using overlap of sky localization probability maps for filtering potentially lensed pairs of gravitational-wave signals
Henry W. Y. Wong, Lok W. L. Chan, Isaac C. F. Wong +2
Strong gravitational lensing creates multiple images of a gravitational wave transient. The current state-of-the-art method for identifying such lensing events is a computationally…
Optimal Sensor Fusion Method for Active Vibration Isolation Systems in Ground-Based Gravitational-Wave Detectors
T. T. L. Tsang, T. G. F. Li, T. Dehaeze +1
Sensor fusion is a technique used to combine sensors with different noise characteristics into a super sensor that has superior noise performance. To achieve sensor fusion, complem…
On the identification of individual gravitational wave image types of a lensed system using higher-order modes
Justin Janquart, Eungwang Seo, Otto A. Hannuksela +2
Similarly to light, gravitational waves can be gravitationally lensed as they propagate near massive astrophysical objects such as galaxies, stars, or black holes. In recent years,…
An extension of Gmunu: General-relativistic resistive magnetohydrodynamics based on staggered-meshed constrained transport with elliptic cleaning
Patrick Chi-Kit Cheong, David Yat Tung Pong, Anson Ka Long Yip +1
We present the implementation of general-relativistic resistive magnetohydrodynamics solvers and three divergence-free handling approaches adopted in the General-relativistic multi…
Improving Detection of Gravitational wave Microlensing Using Repeated Signals Induced by Strong Lensing
Eungwang Seo, Otto A. Hannuksela, Tjonnie G. F. Li
Microlensing imprints by typical stellar mass lenses on gravitational waves are challenging to identify in the LIGO and Virgo frequency band because such effects are weak. However,…
Investigation of the effects of non-Gaussian noise transients and their mitigation in parameterized gravitational-wave tests of general relativity
Jack Y. L. Kwok, Rico K. L. Lo, Alan J. Weinstein +1
The detection of gravitational waves from compact binary coalescence by Advanced LIGO and Advanced Virgo provides an opportunity to study the strong-field, highly relativistic regi…
Signal Space in the Triangular Network of Einstein Telescope
Isaac C. F. Wong, Tjonnie G. F. Li
The proposed third-generation gravitational-wave detectors Einstein Telescope will have a triangular design that consists of three colocated interferometers. Summing the strain out…
Searching for ultralight bosons with supermassive black hole ringdown
Adrian Ka-Wai Chung, Joseph Gais, Mark H. Y. Cheung +1
One class of competitive candidates for dark matter is ultralight bosons. If they exist, these bosons may form long-lived bosonic clouds surrounding rotating black holes via superr…
Null-stream-based Bayesian Unmodeled Framework to Probe Generic Gravitational-wave Polarizations
Isaac C. F. Wong, Peter T. H. Pang, Rico K. L. Lo +2
We present a null-stream-based Bayesian unmodeled framework to probe generic gravitational-wave polarizations. Generic metric theories allow six gravitational-wave polarization sta…
Lensing of Gravitational Waves as a Novel Probe of Graviton Mass
Ka-Wai Chung, Tjonnie Guang Feng Li
The diffraction patterns of lensed gravitational waves encode information about their propagation speeds. If gravitons have mass, the dispersion relation and speed of gravitational…
