Shadow images of Kerr-like wormholes

Understand

Investigations of shadows of astrophysical entities constitute a major source of insight into the evolution of compact objects.

• Such effects depend on the nature of the compact object and arise on account of the strong gravitational lensing that casts a shadow on the bright background.
• We consider the Kerr-like wormhole spacetime (Phys.\ Rev.\ D 97:024040, 2018), which is a modification of the Kerr black hole that degenerates into wormholes for nonzero values of the deviation parameter $\lambda^2$.
• The results suggest that the Kerr spacetime can reproduce far away from the throat of the wormhole.
