Discovering gravitational waveform distortions from lensing: A deep dive into GW231123
Juno C. L. Chan, Jose MarÃa Ezquiaga, Rico K. L. Lo +3
Gravitational waves (GWs) are unique messengers as they travel through the Universe without alteration except for gravitational lensing. Their long wavelengths make them susceptibl…
Effects of Galaxy Cluster Structure on Lensed Gravitational Waves
Luka Vujeva, Jose MarÃa Ezquiaga, Rico K. L. Lo +1
Strong gravitational lenses come in many forms, but are typically divided into two populations: galaxies, and groups and clusters of galaxies. The largest objects in the Universe (…
TESLA-X: An effective method to search for sub-threshold lensed gravitational waves with a targeted population model
Alvin K. Y. Li, Juno C. L. Chan, Heather Fong +3
Strong gravitational lensing can produce copies of gravitational-wave signals from the same source with the same waveform morphologies but different amplitudes and arrival times. S…
Lensing and wave optics in the strong field of a black hole
Juno C. L. Chan, Conor Dyson, Matilde Garcia +2
Gravitational waves (GWs) are lensed by matter, offering a unique probe of both the large-scale structure of the Universe and the fundamental properties of GW propagation. GWs can…
LensingFlow: An Automated Workflow for Gravitational Wave Lensing Analyses
Mick Wright, Justin Janquart, Paolo Cremonese +18
In this work, we present LensingFlow. This is an implementation of an automated workflow to search for evidence of gravitational lensing in a large series of gravitational wave eve…
Observational Signatures of Highly Magnified Gravitational Waves from Compact Binary Coalescence
Rico K. L. Lo, Luka Vujeva, Jose MarÃa Ezquiaga +1
Gravitational lensing has empowered telescopes to discover astronomical objects that are otherwise out of reach without being highly magnified by foreground structures. While we ex…
