On the red--shift emission from the black hole horizons replicas
D. Pugliese, Z. Stuchlik
We examine the red-shift emission from special orbits (horizons replicas) where photons have the same angular velocity, in magnitude, as those of the Kerr black hole (BH) Killing h…

Inter--disks inversion surfaces
D. Pugliese, Z. Stuchlik
We consider a counter--rotating torus orbiting a central Kerr black hole (\textbf{BH}) with dimensionless spin , and its accretion flow into the \textbf{BH}, in an agglomerate o…

Constraining photon trajectories in black hole shadows
D. Pugliese, Z. Stuchlık
We examine the shadow cast by a Kerr black hole, focusing on constraints on photons corresponding to different shadow boundaries. The photons are related to different orbital range…
