Abstract

V originále

We investigate the effect of a reflective firewall surrounding the Kerr black hole. For a perfect fluid torus model, we construct a specific intensity map and corresponding specific intensity profile for impact parameter β = 0. We show that the “mirror” creates additional multi-ring structures in the image area below the photon orbit. We quantitatively show this effect in terms of the profile of the specific intensity Iν0 (α, β = 0) and show that the visibility of this multi-ring structure depends on the reflection efficiency of the mirror.
