An Analytic Study on Strong Field Lensing by Wormholes as Black Hole Foils

  • Amrita Bhattacharya

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 \(\uplambda \sim {10}^{-3}\) .
