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…

Horizon replicas in black hole shadows
D. Pugliese, H. Quevedo
Recently, new exploratory channels have opened up for the physics of highly compact objects, such as gravitational waves and black hole shadows. Moreover, more precise analysis and…
