Gravitational lensing by a regular black hole
gravitational lensing black hole physics regular solutions
2010/12/20
In this paper, we study a regular Bardeen black hole as a gravitational lens. We find the strong deflection limit for the deflection angle, from which we obtain the positions and
magnifications of th...
Strong gravitational lensing across dilaton anti-de Sitter black hole
anti de Sitter gravitational lensing black holes
2010/3/18
In this work we investigate gravitational lensing effect in strong field region around a dilaton black holes in an anti de Sitter (ADS) space. We also analyse the dependence of the radius of the photo...
