Gravitational lensing by wormholes
We have investigated the gravitational lensing by two wormholes, viz., Janis Newman-Winnicour (JNW) wormhole and Ellis wormhole. The deflection angle in the strong field limit is calculated and various lens parameters of two wormholes are compared. It is shown that the JNW wormhole exhibits the relativistic images, while the Ellis wormhole does not have any relativistic images due to the absenc...
متن کاملGravitational Lensing by Wormholes
Abstract. Natural wormholes and its astrophysical signatures have been sugested in various oportunities. By applying the strong field limit of gravitational lensing theory, we calculate the deflection angle produced by Morris-Thorne wormholes in asimptotically flat space-times. The results show that wormholes act like convergent lenses. Therefore it is hard to distinguish them from black holes ...
متن کاملGravitational memory of natural wormholes
A traversable wormhole solution of general scalar–tensor field equations is presented. We have shown, after a numerical analysis for the behavior of the scalar field of Brans-Dicke theory, that the solution is completely singularity– free. Furthermore, the analysis of more general scalar field dependent coupling constants indicates that the gravitational memory phenomenon may play an important ...
متن کاملBlack Holes, Wormholes, and Gravitational Collapse
We study a possibility of the dynamical formation of traversable wormholes from gravitationally collapsing exotic matter clouds. For generic metric ansatz of exterior spacetimes, a crucial constraint that black holes and wormholes should satisfy is obtained through the junction conditions on the edge. As a result, it is shown that the wormhole geometry cannot be formed by following the usual Op...
