Strong lensing and shadow of Ayon-Beato–Garcia (ABG) nonsingular black hole
نویسندگان
چکیده
We study nonsingular black holes viewed from the point of view Ayon-Beato-Garcia (ABG) nonlinear electrodynamics (NLED) and present a complete their corresponding strong gravitational lensing. The NLED modifies photon's geodesic, our calculations show that such effect increases photon sphere radius image separation, but decreases magnification. also ABG's shadow is not compatible with bound estimates Sgr A* Keck VLTI (Very Large Telescope Interferometer). Thus, possibility being ABG hole ruled out.

Gravitational Lensing in Presence of Plasma:Strong Lens Systems, Black Hole Lensing and Shadow
In this article, we present an overview of the new developments in problems of the plasma influence on the effects of gravitational lensing, complemented by pieces of new material and relevant discussions. Deflection of light in the presence of gravity and plasma is determined by a complex combination of various physical phenomena: gravity, dispersion, refraction. In particular, the gravitation...
متن کاملNonsingular black hole evaporation and "stable" remnants.
We examine the evaporation of two–dimensional black holes, the classical space–times of which are extended geometries, like for example the two–dimensional section of the extremal Reissner–Nordstrom black hole. We find that the evaporation in two particular models proceeds to a stable end–point. This should represent the generic behavior of a certain class of two–dimensional dilaton–gravity mod...

متن کاملStability of a vacuum nonsingular black hole
This is the first of series of papers in which we investigate stability of the spherically symmetric space-time with de Sitter center. Geometry, asymptotically Schwarzschild for large r and asymptotically de Sitter as r → 0, describes a vacuum nonsingular black hole for m ≥ mcr and particle-like self-gravitating structure for m < mcr where a critical value mcr depends on the scale of the symmet...
متن کاملTwo Black Hole Holography, Lensing and Intensity
We numerically verify the analysis of the “expanding horizon” theory of Susskind in relation to the ’t Hooft holographic conjecture. By using a numerical simulation to work out the image formed by two black holes upon a screen very far away, it is seen that it is impossible for a horizon to hide behind another. We also compute the intensity distribution of such an arrangement. 1 E-mail: markj@p...
