Essentials of Strong Gravitational Lensing [PDF]
Space Science ReviewsOf order one in $10^{3}$ 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 wormholes [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 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.

Line-of-sight effects in strong gravitational lensing [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 While most strong-gravitational-lensing systems may be roughly modelled by a single massive object between the source and the observer, in the details all the structures near the light path contribute to the observed images.

Strong gravitational lensing of explosive transients [PDF]
Reports on Progress in Physics, 2019 Recent rapid progress in time domain surveys makes it possible to detect various types of explosive transients in the Universe in large numbers, some of which will be gravitationally lensed into multiple images. Although a large number of strongly lensed

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 significantly to the lensing potential will be detected in the large sample of lens systems compiled ...

Simulations of strong gravitational lensing with substructure [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 Galactic sized gravitational lenses are simulated by combining a cosmological N-body simulation and models for the baryonic component of the galaxy. The lens caustics, critical curves, image locations and magnification ratios are calculated by ray-shooting on an adaptive grid.

Shadows and Strong Gravitational Lensing by Van Derwaals Black Hole in Homogeneous Plasma [PDF]
Social Science Research Network, 2022 In this paper, we first analyze the horizon structure of the Van der Waals(VdW) black hole and then investigate its shadow in the absence of a plasma medium as well as the presence of a homogeneous plasma medium.
