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…
Dark Matter Subhalos and Higher Order Catastrophes in Gravitational Wave Lensing
Luka Vujeva, Jose MarÃa Ezquiaga, Daniel Gilman +2
Gravitational lensing is an invaluable probe of the nature of dark matter, and the structures it forms. Lensed gravitational waves in particular allow for unparalleled sensitivity…
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 (…
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…
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…
