Wave optical imaging by point-source scattering for a TNdS black hole
Abstract
In our work, we present a calculation based on an exact, non-approximated wave equation, as described by the Teukolsky equation, for a Taub-NUT-de Sitter spacetime. We observe the scattering of a monochromatic point source by an observer located at a greater distance from the black hole, and examine the wave-optical images by a single source and by multiple sources.
