Strong Gravitational Lensing of Gravitational Waves: A Review

Universe, 2023
The first successful detection of gravitational waves (GWs) opened up a new window to study a realm of the most violent phenomena in the universe, such as coalescences of binary black holes (BH–BH), binary neutron stars (NS–NS), and mixed (BH–NS) systems,

Strong Gravitational-wave Lensing Posterior Odds

The Astrophysical Journal
Like light, gravitational waves are gravitationally lensed by intervening massive astrophysical objects—such as galaxies, clusters, black holes, and stars—resulting in a variety of potentially observable gravitational-wave lensing signatures.

Strong gravitational lensing by wormholes [PDF]

Journal of Cosmology and Astroparticle Physics, 2023
We study strong gravitational lensing by a class of static wormhole geometries. Analytical approaches to the same are developed, and the results differ substantially from strong lensing by black holes, first reported by Bozza.

Strong gravitational lensing with the SKA [PDF]

Proceedings of Advancing Astrophysics with the Square Kilometre Array — PoS(AASKA14), 2014
Strong gravitational lenses provide an important tool to measure masses in the distant Universe, thus testing models for galaxy formation and dark matter; to investigate structure at the Epoch of Reionization; and to measure the Hubble constant and ...

PyAutoLens: Open-Source Strong Gravitational Lensing [PDF]

Journal of Open Source Software, 2021
Strong gravitational lensing, which can make a background source galaxy appears multiple times due to its light rays being deflected by the mass of one or more foreground lens galaxies, provides astronomers with a powerful tool to study dark matter ...

Image Simulations for Strong and Weak Gravitational Lensing [PDF]

Symmetry, 2020
Gravitational lensing has been identified as a powerful tool to address fundamental problems in astrophysics at different scales, ranging from exoplanet identification to dark energy and dark matter characterization in cosmology.

Strong gravitational lensing with SKA [PDF]

New Astronomy Reviews, 2004
The advent of new observational facilities in the last two decades has allowed the rapid discovery and high-resolution optical imaging of many strong lens systems from galaxy to cluster scales, as well as their spectroscopic follow-up.

Essentials of strong gravitational lensing

Space Science Reviews
Of order one in 10^3 quasars and high-redshift galaxies appears in the sky as multiple images as a result of gravitational lensing by unrelated galaxies and clusters that happen to be in the foreground.

Strong gravitational lensing by multiple galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2001
We discuss strong gravitational lensing by multiple objects along any line of sight. The probability for strong gravitational lensing by more than one lens is small, but a number of strong lens systems in which more than one separate lens contribute ...

Strong Gravitational Lensing and Microlensing of Supernovae. [PDF]

Space Sci Rev
AbstractStrong gravitational lensing and microlensing of supernovae (SNe) are emerging as a new probe of cosmology and astrophysics in recent years. We provide an overview of this nascent research field, starting with a summary of the first discoveries of strongly lensed SNe. We describe the use of the time delays between multiple SN images as a way to
