Observing black hole phase transitions in extended phase space and holographic thermodynamics approaches from optical features

Abstract The phase transitions of charged Anti-de Sitter (AdS) black holes are characterized by studying null geodesics in the vicinity of the critical curve of photon trajectories around black holes as well as their optical appearance as the black hole images. In the present work, the critical para...
