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…
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…
Dark matter effect on black hole accretion disks
D. Pugliese, Z. Stuchlík
Comparing different dark matter (DM) models, we explore the DM influence on black hole (BH) accretion disk physics, considering corotating and counterrotating thick accretion tori…
On photons and matter inversion spheres from complex super-spinars accretion structures
D. Pugliese, Z. Stuchlik
Our analysis focus on the dragging effects on the accretion flows and jet emission in Kerr super-spinars. These attractors are characterized by peculiar accretion structures as dou…
Naked singularities and black hole Killing horizons
Daniela Pugliese, Hernando Quevedo
In this chapter, we study special photon orbits defined by means of Killing vectors and present a framework based on the properties of such null orbits. For concreteness, we restri…
