Influence of a plasma on the observational signature of a high-spin Kerr black hole

To approach a more reliable observational signature of a high-spin Kerr black hole, one should take into account the effects of its surroundings. To this end, we study in this paper the influence of a surrounding plasma. We consider its refractive and dispersive effects on photon trajectories and ig...
