Shadows of rotating Einstein-Maxwell-dilaton black holes surrounded by a plasma
Javier Badía, Ernesto F. Eiroa
We consider rotating charged black holes with a scalar dilaton field and surrounded by plasma, with the purpose of studying their shadows. The corresponding metric has been previou…
Shadow of a charged black hole surrounded by an anisotropic matter field
Javier Badía, Ernesto F. Eiroa
A certain type of matter with anisotropic pressures can add to the Reissner-Nordström metric a term proportional to a power of the radial coordinate. Using the standard method of s…
Shadow of black holes with a plasma environment in 4D Einstein-Gauss-Bonnet gravity
Javier Badía, Ernesto F. Eiroa
We study the shadow cast by rotating black holes surrounded by plasma in the context of the 4D Einstein-Gauss-Bonnet theory of gravity. The metric for these black holes results fro…
Shadow of axisymmetric, stationary and asymptotically flat black holes in the presence of plasma
Javier Badía, Ernesto F. Eiroa
We study the shadow produced by a class of rotating black holes surrounded by plasma. The metric for these black holes arises by applying the Newman-Janis algorithm to a family of…
Influence of an anisotropic matter field on the shadow of a rotating black hole
Javier Badía, Ernesto F. Eiroa
In this paper, we study the shadow produced by rotating black holes with charge in the presence of an anisotropic matter field. We obtain the apparent shape and the corresponding o…
Gravitational lensing by a Horndeski black hole
Javier Badía, Ernesto F. Eiroa
In this article we study gravitational lensing by non-rotating and asymptotically flat black holes in Horndeski theory. By adopting the strong deflection limit, we calculate the de…
