Turning Selection Bias into a New Statistic: Asymmetry and Fringes of Lensed Gravitational Waves
Juno C. L. Chan, Elwin K. Y. Li
Gravitational waves (GWs) propagating across the Universe can be distorted by intervening lenses, producing characteristic wave-optics signatures. These effects are not incorporate…
Discovering gravitational waveform distortions from lensing: A deep dive into GW231123
Juno C. L. Chan, Jose María 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…
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…
Multi-messenger Gravitational Lensing
Graham P. Smith, Tessa Baker, Simon Birrer +38
We introduce the rapidly emerging field of multi-messenger gravitational lensing - the discovery and science of gravitationally lensed phenomena in the distant universe through the…
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…
Effects of Galaxy Cluster Structure on Lensed Gravitational Waves
Luka Vujeva, Jose María 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 (…
Detectability of lensed gravitational waves in matched-filtering searches
Juno C. L. Chan, Eungwang Seo, Alvin K. Y. Li +2
Gravitational lensing by compact, small-scale intervening masses causes frequency-dependent distortions to gravitational-wave events. The optimal signal-to-noise ratio (SNR) is oft…
What is the nature of GW230529? An exploration of the gravitational lensing hypothesis
Justin Janquart, David Keitel, Rico K. L. Lo +26
On the 29th of May 2023, the LIGO-Virgo-KAGRA Collaboration observed a compact binary coalescence event consistent with a neutron star-black hole merger, though the heavier object…
Observational Signatures of Highly Magnified Gravitational Waves from Compact Binary Coalescence
Rico K. L. Lo, Luka Vujeva, Jose María 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…
Observation of Gravitational Waves from the Coalescence of a Compact Object and a Neutron Star
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1793
We report the observation of a coalescing compact binary with component masses and (all measurements quoted at the 90% credible le…
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…
Targeted Sub-threshold Search for Strongly-lensed Gravitational-wave Events
Alvin K. Y. Li, Rico K. L. Lo, Surabhi Sachdev +4
Strong gravitational lensing of gravitational waves can produce duplicate signals separated in time with different amplitudes. We consider the case in which strong lensing produces…
