Optical properties of a Brane-World black hole as photons couple to the Weyl tensor
Abstract In this article, we have investigated the equations of motion of the photons coupled to Weyl tensor by the geometric optics approximation and the corresponding shadow in a Brane-World black hole spacetime. It is shown that there exists a double shadow for a black hole since the coupling pho...
