New rotating Lorentzian wormhole spacetime
arXiv:2411.09202 · doi:10.1103/PhysRevD.111.064010
Abstract
A rotating version of a known static, spherically symmetric, zero Ricci scalar Lorentzian wormhole is constructed. It turns out that for this given non-rotating geometry, the standard Newman-Janis algorithm does not produce a rotating wormhole and, therefore, the method pioneered by Azreg-Aïnou has to be used. The rotating spacetime thus obtained is shown to be regular with wormhole features, though it is no longer a spacetime. The required matter is found to violate the energy conditions, as expected. A few other characteristic properties of this new rotating spacetime are mentioned. Finally, we calculate the shadow for this geometry and discuss its features {\em vis-a-vis} the Kerr geometry and available event horizon telescope observations.
