Strong-Field Gravitational-Wave Lensing from Ray-Traced Arrival-Time Surfaces
Luka Vujeva, João S. Santos, Brian C. Seymour
The diffraction integral formalism has been greatly successful in describing gravitational wave lensing effects in scenarios where the wavelength of the signal is comparable to the…
Strong Field Gravitational Lensing in Full Wave Optics
João Sieiro dos Santos, Luka Vujeva
Compact binaries evolving in the vicinity of massive black holes may be commonplace in the Universe, and their gravitational waves carry signatures of their environment. We study t…
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 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…
Dark Matter Subhalos and Higher Order Catastrophes in Gravitational Wave Lensing
Luka Vujeva, Jose María 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…
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…
Diffraction around caustics in gravitational wave lensing
Jose María 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…
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…
Constraining Proper Motion of Strongly Lensed Eccentric Binary Mergers using Doppler Triangulation
Johan Samsing, Lorenz Zwick, Pankaj Saini +5
Strong lensing of gravitational wave (GW) sources allows the observer to see the GW source from different lines-of-sight (LOS) through the corresponding images, which provides a wa…
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 (…
Measuring the Transverse Velocity of Strongly Lensed Gravitational Wave Sources with Ground Based Detectors
Johan Samsing, Lorenz Zwick, Pankaj Saini +7
Observations of strongly gravitationally lensed gravitational wave (GW) sources provide a unique opportunity for constraining their transverse motion, which otherwise is exceedingl…
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…
lenscat: a Public and Community-Contributed Catalog of Known Strong Gravitational Lenses
L. Vujeva, R. K. L. Lo, J. M. Ezquiaga +1
We present lenscat, a public and community-contributed catalog of strong gravitational lenses found by electromagnetic surveys. The main objective of lenscat is to compile a simple…
Mapping a lower limit on the mass fraction of the cold neutral medium using Fourier transformed HI 21cm emission line spectra: Application to the DRAO Deep Field from DHIGLS and the HI4PI survey
Antoine Marchal, Peter G. Martin, Marc-Antoine Miville-Deschênes +4
We develop a new method for spatially mapping a lower limit on the mass fraction of the cold neutral medium by analyzing the amplitude structure of , the Fourier tra…
Efficient survey design for finding high-redshift galaxies with JWST
Luka Vujeva, Charles L. Steinhardt, Christian Kragh Jespersen +9
Several large JWST blank field observing programs have not yet discovered the first galaxies expected to form at . This has motivated the search for more effecti…
