Analytic Investigation of the Imprints of Dark Energy and Charge on the Kerr–Newmann–De Sitter Black-Hole Photon Ring

In 2019, the Event Horizon Telescope (EHT) released the first image of a black hole, sparking huge interest in the study of black-hole images. We present analytical solutions to the null geodesic equations for Kerr–Newman–de Sitter black holes derived using Jacobi elliptic functions. Using these sol...
