Strong Gravitational Lensing in the Einstein-Proca Theory [PDF]

International Journal of Theoretical Physics, 2014
Adopting the strong field limit approach, we investigate the strong gravitational lensing of a spherically symmetric spacetime in the Einstein-Proca theory. With the strong field limit coefficient, three observable quantities are obtained, which are the innermost relativistic image, the deflection angle and the ratio of the flux.

Strong Gravitational Lensing as a Probe of Dark Matter

Space Science Reviews
AbstractDark matter structures within strong gravitational lens galaxies and along their lines of sight leave a gravitational imprint on the multiple images of lensed sources. Strong gravitational lensing provides, therefore, a key test of different dark matter models.

Gravitational lensing in the presence of plasmas and strong gravitational fields

Gravitation and Cosmology, 2014
The theory of gravitational lensing is well developed for light propagation in vacuum in the approximation of weak deflection. We discuss two ways of extending the studies of usual gravitational lens theory which were recently theoretically developed. One way is to go beyond the weak deflection approximation and consider relativistic images formed by ...

Strong gravitational lensing by multiple galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2001
We discuss strong gravitational lensing by multiple objects along any line of sight. The probability for strong gravitational lensing by more than one lens is small, but a number of strong lens systems in which more than one separate lens contribute significantly to the lensing potential will be detected in the large sample of lens systems compiled ...
