Gravitational Lensing in Astronomy [PDF]

open access: yesLiving Reviews in Relativity, 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 ...

Gravitational Lensing [PDF]

open access: yesClassical and Quantum Gravity, 2010
Gravitational lensing has developed into one of the most powerful tools for the analysis of the dark universe. This review summarises the theory of gravitational lensing, its main current applications and representative results achieved so far.

Gravitational lensing. [PDF]

open access: yesProc 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.

Multi-messenger gravitational lensing. [PDF]

open access: yesPhilos Trans A Math Phys Eng Sci
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 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 [PDF]

open access: yesProceedings of 8th European VLBI Network Symposium — PoS(8thEVN), 2007
This is a short and biased review of gravitational lensing with emphasis on the radio and especially VLBI aspects. We briefly explain the basic idea and give a short sketch of the discovery of the first lens, before we more systematically discuss the ...

Gravitational Lensing from a Spacetime Perspective [PDF]

open access: yesLiving Reviews in Relativity, 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 ...

Geometric Outlines of the Gravitational Lensing and Its Astronomic Applications

open access: yesUniverse, 2023
Gravitational lensing is a topic of great application value in the field of astronomy. The properties and research methods of gravitational lensing are closely related to the geometric and relativistic characteristics of the background universe.

Gravitational Lensing of Acoustic Charged Black Holes

open access: yesThe Astrophysical Journal, 2023
We study the gravitational lensing of acoustic charged black holes in strong and weak field limit approximations. For this purpose, we first numerically obtain the deflection limit coefficients and deflection angle in the strong field limit.
