Thermal Image and Phase Transitions of Charged AdS Black Holes using Shadow Analysis

Understand

We investigate the relations between the black hole shadow and charged AdS black hole critical behaviour in the extended phase space.

• Using the thermo-shadow formalism built-in [1], we reveal that the shadow radius can be considered as an efficient tool to study thermodynamical black hole systems.
• Based on such arguments, we build a thermal profile by varying the RN-AdS black hole temperature on the shadow silhouette.
• Among others, the Van der Waals-like phase transition takes place.
