The Shadow of Charged Traversable Wormholes

TL;DR

This paper analyzes the shadow of a charged Morris-Thorne wormhole, revealing how its charge influences the shape and size of the observed shadow, with implications for understanding exotic spacetime geometries.

Contribution

It provides a detailed analysis of the geodesic properties and shadow structure of charged wormholes, highlighting the effects of charge on observable features.

Findings

Shadow size scales proportionally with charge.

Some light rays always reach the observer regardless of viewing angle.

The shadow structure remains consistent across different charge values.

Abstract

We compute the shadow cast by a charged Morris-Thorne wormhole when the light source is a star located beyond the mouth which is opposite to the observer. First, we provide an extensive analysis of the geodesic properties of the spacetime, both for null and massive particles. The geometrical properties of this solution are such that independently of the viewing angle, some light rays always reach the observer. Additionally, the structure of the images is preserved among the different values of the charge and scales proportionally to the charge value.
