Gravitational Lensing in Astronomy. [PDF]
Living Rev Relativ, 1998 Deflection of light by gravity was predicted by General Relativity and observationaly confirmed in 1919. In the following decades various aspects of the gravitational lens effect were explored theoretically, among them the possibility of multiple or ring-like images of background sources, the use of lensing as a gravitational telescope on very faint ...

Proc Natl Acad Sci U S A, 2013 Since Galileo, the arrays of lenses in telescopes have revolutionized the way we see planets, moons, and the universe. Now gravitational lenses made of warped spacetime are helping astronomers peer into the farthest corners of the cosmos.

A review on analytical studies in gravitational lensing [PDF]
Frontiers in Physics, 2023 In this study, we review some current studies on gravitational lensing for black holes, mainly in the context of general relativity. We mainly focus on the analytical studies related to lensing with references to observational results.

Gravitational Lensing of Continuous Gravitational Waves [PDF]
Universe, 2021 Continuous gravitational waves are analogous to monochromatic light and could therefore be used to detect wave effects such as interference or diffraction. This would be possible with strongly lensed gravitational waves.

Gravitational lensing by a black-bounce-Reissner–Nordström spacetime
European Physical Journal C: Particles and Fields, 2022 We investigate the weak and strong deflection gravitational lensing by a black-bounce-Reissner–Nordström spacetime and obtain their lensing observables. Assuming the supermassive black holes in the Galactic Center and at the center of M87, Sgr A* and M87*

The Scales of Gravitational Lensing [PDF]
Universe, 2016 After exactly a century since the formulation of the general theory of relativity, the phenomenon of gravitational lensing is still an extremely powerful method for investigating in astrophysics and cosmology.

Multi-messenger gravitational lensing. [PDF]
Philos Trans A Math Phys Eng SciWe introduce the rapidly emerging field of multi-messenger gravitational lensing—the discovery and science of gravitationally lensed phenomena in the distant universe through the combination of multiple messengers. This is framed by gravitational lensing phenomenology that has grown since the first discoveries in the twentieth century, messengers that ...

Gravitational Lensing from a Spacetime Perspective. [PDF]
Living Rev Relativ, 2004 The theory of gravitational lensing is reviewed from a spacetime perspective, without quasi-Newtonian approximations. More precisely, the review covers all aspects of gravitational lensing where light propagation is described in terms of lightlike ...

The Atacama Cosmology Telescope: DR6 Gravitational Lensing Map and Cosmological Parameters [PDF]
Astrophysical Journal, 2023 We present cosmological constraints from a gravitational lensing mass map covering 9400 deg2 reconstructed from measurements of the cosmic microwave background (CMB) made by the Atacama Cosmology Telescope (ACT) from 2017 to 2021.
