Strong gravitational lensing for photons coupled to Weyl tensor in a regular phantom black hole
Abstract We study strong gravitational lensing for photons coupled to Weyl tensor in a regular phantom black hole spacetime. It is generally accepted that photons with different polarizations have different trajectories which yields a phenomenon of birefringence. As a result, there are two sets of r...
