Probability of gravitational-wave lensing by intermediate-mass black holes and globular clusters
Luka Vujeva, Jose María Ezquiaga, Rico K. L. Lo +1
Strongly lensed gravitational waves (GWs) are powerful probes of substructure in the lens. Intermediate-mass black holes (IMBHs) are postulated to be efficient lenses that may dist…
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 (…
Diffraction around caustics in gravitational wave lensing
Jose MarÃa Ezquiaga, Rico K. L. Lo, Luka Vujeva
Gravitational lensing magnification is maximal around caustics. At these source locations, an incoming wave from a point source would formally experience an infinite amplification…
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…
