Rotating Brane-World Black Hole Lensing in the Strong Deflection Limit

Abstract

We consider the metric describing a rotating black hole with tidal charge in the Randall- Sundrum brane world. We study strong field gravitational lensing by this black hole in the quasi-equatorial plane. We compute the angular position of the relativistic caustic points, magnification of the relativistic images and also the critical curves as functions of the metric parameters including the tidal charge. Certain interesting comparisons of the lensing quantities are found with their corresponding properties for the Kerr black hole.
