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 ...

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 ...

Strong Gravitational-wave Lensing Posterior Odds
The Astrophysical JournalLike light, gravitational waves are gravitationally lensed by intervening massive astrophysical objects—such as galaxies, clusters, black holes, and stars—resulting in a variety of potentially observable gravitational-wave lensing signatures.

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.

AIP Conference Proceedings, 2009 Gravitational lensing of the cosmic microwave background by large‐scale structure in the late universe is both a source of cosmological information and a potential contaminant of primordial gravity waves. Because lensing imprints growth of structure in the late universe on the CMB, measurements of CMB lensing will constrain parameters to which the CMB ...

Gravitational lensing derives its simplicity from some basic assumptions that are satisfied by most physical situations.The thin lens approximation and weak field approximations were used to build the whole theory and explain the phenomenology up to ...

, 2017 Gravitational lensing is a consequence of general relativity, where the gravitational force due to a massive object bends the paths of light originating from distant objects lying behind it.

Search for lensing signatures in the gravitational-wave observations from the first half of LIGO–Virgo's third observing run [PDF]
, 2021 We search for signatures of gravitational lensing in the gravitational-wave signals from compact binary coalescences detected by Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) and Advanced Virgo during O3a, the first half of their ...

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

Galaxy-Galaxy weak gravitational lensing in cluster environment [PDF]
, 2012 An investigation was carried out into the phenomenon of galaxy-galaxy weak lensing in a sample of 10 X-ray selected galaxy clusters. Using high resolution Hubble Space Telescope imaging data and mathematical techniques described within, the feasibility ...
