“…The shadow of the sphericallysymmetric Ellis wormholes surrounded by plasma has been studied by Perlick et al (2015). The gravitational lensing and images of black hole in plasma environment has been recently studied in Bisnovatyi-Kogan and Tsupko (2010), Tsupko and Bisnovatyi-Kogan (2012), Morozova et al (2013), Perlick et al (2015), Er and Mao (2014), Atamurotov et al (2015), Rogers (2015). The transfer of radiation in an isotropic refractive, and dispersive medium using the Hamiltonian approach in a curved spacetime is studied in Bicak and Hadrava (1975) by applying the generalrelativistic kinetic theory.…”

The massless particle motion around rotating wormhole in the presence of plasma environment has been studied. It has been shown that the presence of the plasma decreases the inner radius of the circular orbits of photons around rotating wormhole. The shadow cast by rotating wormhole surrounded by inhomogeneous plasma with the radial power-law density has been explored. It has been shown that the shape and size of the wormhole shadow is distorted and changed depending on i) plasma parameters, ii) wormhole rotation and iii) inclination angle between observer plane and axis of rotation of wormhole. As an example we have considered an inverse radial distribution of the plasma density and different types of the wormhole solution.

“…Morozova et al 54 generalized the calculation to the Kerr metric off the equatorial plane, assuming that the black hole is slowly rotating. For recent suggestions of the ways to actually observe the effects of plasma on light rays, we refer to Er and Mao, 55 and Rogers, 56 see also subsections 3.2 and 3.3.…”

This article is a rapporteur review of selected talks presented at the session 'Gravitational lensing: theory and numerical modeling' of the Fourteenth Marcel Grossmann Meeting (MG14) as well as discussion of general ideas of related topics. We consider the influence of plasma on various gravitational lensing effects, including strong lensing systems and black hole shadows. We discuss recent developments in gravitational lensing beyond the small deflection regime, as well as some other aspects of this field. New results in modeling strong lensing systems and microlensing are presented.

Optical properties of black holes in the presence of a plasma: The shadow

We have studied photon motion around axially symmetric rotating Kerr black hole in the presence of plasma with radial power-law density. It is shown that in the presence of plasma the observed shape and size of shadow changes depending on i) plasma parameters, ii) black hole spin and iii) inclination angle between observer plane and axis of rotation of black hole. In order to extract pure effect of plasma influence on black hole image the particular case of the Schwarzschild black hole has also been investigated and it has been shown that i) the photon sphere around the spherical symmetric black hole is left unchanged under the plasma influence, ii) however the Schwarzschild black hole shadow size in plasma is reduced due to the refraction of the electromagnetic radiation in plasma environment of black hole. The study of the energy emission from the black hole in plasma shows that in the presence of plasma the maximal energy emission rate from the black hole decreases.PACS numbers: 95.30.Sf; 98.62.Sb
