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: 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. [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: yesAstrophysics and Space Science, 2001
AbstractIn the roughly 20 years of its existence as an observational science, gravitational lensing has established itself as a valuable tool in many astrophysical fields. In the introduction of this review we briefly present the basics of lensing. Then it is shown that the two propagation effects, lensing and scintillation, have a number of properties

Inverting Gravitational Lenses [PDF]

open access: yesSIAM Review, 2002
Summary: Gravitational lensing provides a powerful tool to study a number of fundamental questions in astrophysics. Fortuitously, one can begin to explore some nontrivial issues associated with this phenomenon without a lot of very sophisticated mathematics, making an elementary treatment of this topic tractable even to senior undergraduates. We give a

Exploring gravitational lensing [PDF]

open access: yesEuropean Journal of Physics, 2019
In this article, we discuss the idea of gravitational lensing, from a systematic, historical and didactic point of view. We show how the basic lensing equation together with the concepts of geometrical optics opens a space of implications that can be explored along different dimensions.

Toward an Optimal Reconstruction of the Shear Field with PDF-folding

open access: yesThe Astrophysical Journal, 2023
Weak lensing provides a direct way of mapping the density distribution in the Universe. To reconstruct the density field from the shear catalog, an important step is to build the shear field from the shear catalog, which can be quite nontrivial due to ...
