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.

Weak Gravitational Lensing [PDF]
We review theory and applications of weak gravitational lensing. After summarising Friedmann-Lemaitre cosmological models, we present the formalism of gravitational lensing and light propagation in arbitrary space-times. We discuss how weak-lensing effects can be measured.

Gravitational lensing by gravitational waves [PDF]
Gravitational lensing by gravitational wave is considered. We notice that although final and initial direction of photons coincide, displacement between final and initial trajectories occurs.

Gravitational lensing: a unique probe of dark matter and dark energy. [PDF]
I review the development of gravitational lensing as a powerful tool of the observational cosmologist. After the historic eclipse expedition organized by Arthur Eddington and Frank Dyson, the subject lay observationally dormant for 60 years.

Gravitational Lensing in Astronomy. [PDF]
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 by Spherical Lenses [PDF]
In this work we introduced a new proposal to study the gravitational lensing theory by spherical lenses, starting from its surface mass density $ (x)$ written in terms of a decreasing function $f$ of a dimensionless coordinate $x$ on the lens plane.

Gravitational Lensing of Continuous Gravitational Waves [PDF]
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. This article reviews and summarises the theory of gravitational lensing in the context of gravitational waves in two different ...
