An Analytic Study on Strong Field Lensing by Wormholes as Black Hole Foils
摘要
In this paper it is decided to derive the strong field lensing observables for black hole foils which is considered as the Damour-Solodukhin wormhole and also to examine the range of the deviation parameter λ for which it mimics Schwarzschild black holes in both the classical and quantum level. The lensing observables for the black hole \(Sgr{A}^{*}\) residing in our galaxy can be interpreted to provide a numerical expression of \(\uplambda \sim {10}^{-3}\) .
