Gravitational Lensing [PDF]

open access: yesHighlights of Astronomy, 1992
AbstractAtmospheric lensing effects deform our view of distant objects; similarly, without any doubt, gravitational lensing perturbs our view of the distant Universe and affects our physical understanding of various classes of extragalactic objects.

Weak Lensing of the Cosmic Microwave Background by Foreground Gravitational Waves [PDF]

open access: yes, 2006
Weak lensing distortion of the background cosmic microwave background (CMB) temperature and polarization patterns by the foreground density fluctuations is well studied in the literature.

Evolving Morphology of Resolved Stellar Einstein Rings

open access: yesThe Astrophysical Journal, 2023
We consider strong gravitational lensing by nearby stars. Using our wave-optical treatment of lensing phenomena, we study Einstein rings that may form around nearby stellar lenses.

Gravitational lensing and modified Newtonian dynamics [PDF]

open access: yes, 2001
Gravitational lensing is most often used as a tool to investigate the distribution of (dark) matter in the universe, but, if the mass distribution is known a priori, it becomes, at least in principle, a powerful probe of gravity itself.

Aberration in gravitational lensing [PDF]

open access: yesPhysical Review D, 2008
It is known that a relative translational motion between the deflector and the observer affects gravitational lensing. In this paper, a lens equation is obtained to describe such effects on actual lensing observables. Results can be easily interpreted in terms of aberration of light-rays.

Strong Deflection Gravitational Lensing for the Photons Coupled to the Weyl Tensor in a Conformal Gravity Black Hole

open access: yesUniverse, 2023
In the present paper, strong deflection gravitational lensing is studied in a conformal gravity black hole. With the help of geometric optics limits, we have formulated the light cone conditions for the photons coupled to the Weyl tensor in a conformal ...

Shadow and Weak Deflection Angle of a Black Hole in Nonlocal Gravity

open access: yesUniverse, 2022
Black hole shadow and gravitational lensing play important roles in testing gravitational theories in the strong field regime. As the first-order modifications from quantum gravity, the nonlocality can be manifested by black hole shadow and gravitational

Editorial of Modified Theories of Gravity and Cosmological Applications

open access: yesUniverse, 2022
General Relativity is a theory of gravity that describes some of the effects of gravity with high accuracy, such as solar system tests, gravitational lensing, gravitational waves, black holes, deflection angle, etc [...]
