Analytical Approaches to Modeling Thick Photon Rings
Abstract
Abstract General relativity predicts the existence of an infinite number of nested photon rings around black holes, each containing information about the properties of curved space-time. In this paper, analytical models of a thick Gaussian asymmetric photon ring are developed and the visibility function with baselines up to six Earth diameters is calculated.
