Gravitational Lensing in Astronomy [PDF]

Living Reviews in Relativity, 1998
Deflection of light by gravity was predicted by General Relativity and observationally confirmed in 1919. In the following decades, various aspects of the gravitational lens effect were explored theoretically. Among them were: the possibility of multiple or ring-like images of background sources, the use of lensing as a gravitational telescope on very ...

Gravitational lensing. [PDF]

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.

Multi-messenger gravitational lensing. [PDF]

Philos 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 ...

Inverting Gravitational Lenses [PDF]

SIAM 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

Gravitational lensing by wormholes [PDF]

Physical Review D, 2006
Gravitational lensing by traversable Lorentzian wormholes is a ew possibility which is analyzed here in the strong field limit. Wormhole solutions are considered in the Einstein minimally coupled theory and in the brane world model. The observables in both the theories show significant differences from those arising in the Schwarzschild black hole ...

The ‘Gravitational Lensing’ Bibliography [PDF]

Symposium - International Astronomical Union, 1996
We present a non-exhaustive bibliography on “Gravitational Lensing” (GL), totalizing nearly 1500 titles (see Pospieszalska-Surdej et al. 1993 for an earlier version of this bibliography). It also includes recent abstracts of papers dealing with gravitational lensing and submitted to astro-ph@babbage.sissa.it. The GL bibliography is accessible through a

Exploring gravitational lensing [PDF]

European Journal of Physics, 2019
Abstract 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.

Rotation in gravitational lenses [PDF]

Monthly Notices of the Royal Astronomical Society, 2006
Gravitational lensing deflects light. A single lens deflector can only shear images, but cannot induce rotations. Multiple lens planes can induce rotations. Such rotations can be observed in quadruply imaged sources, and can be used to distinguish between two proposed solutions of the flux anomaly problem: substructures in lensing galaxies vs large ...

Investigating gravitational lensing diffraction in the laboratory with structured light [PDF]

EPJ Web of Conferences
We use spatial light modulation to investigate the diffractive effects of gravitational lensing in the laboratory. Using this new platform for laboratory astrophysics, we can overcome the coherence challenges that prevent the observation of diffraction ...
