Braneworld black hole gravitational lens: Strong field limit analysis
Abstract
Description
In this paper, a braneworld black hole is studied as a gravitational lens, using the strong field limit to obtain the positions and magnifications of the relativistic images. Standard lensing and retrolensing situations are analyzed in a unified setting, and the results are compared with those corresponding to the Schwarschild black hole lens. The possibility of observing the strong field images is discussed.
