Reflection-asymmetric wormholes and their double shadows

Understand

We discuss construction and observational properties of wormholes obtained by connecting two Reissner-Nordstrom spacetimes with distinct mass and charge parameters.

• These objects are spherically symmetric, but not reflection-symmetric, as the connected spacetimes differ.
• The reflection-asymmetric wormholes may reflect a significant fraction of the infalling radiation back to the spacetime of its origin.
• We interpret this effect in a simple framework of the effective photon potential.
