Shadow of charged wormholes in Einstein-Maxwell-dilaton theory

Understand

The study of shadow is quite prominent nowadays because of the ongoing Event Horizon Telescope\footnote{https://eventhorizontelescope.org/} observations.

• We construct the shadow images of charged wormholes in Einstein-Maxwell-dilaton (EMD) theory.
• The spacetime metric of the charged wormholes contains three charges: magnetic charge $P$, electric charge $Q$, and dilaton charge $\Sigma$.
• We evaluate the photon geodesics around the charged wormholes.
