Viscosity effects on the shadow of a non-rotating black hole
Sayantani Lahiri, Sergio Gimeno-Soler, Alejandro Cruz-Osorio +2
We study the effect of shear viscosity in stationary magnetized accretion tori on synthetic images of non-rotating black hole shadows. Shear viscosity and spacetime-curvature contr…

Equilibrium models of Weyssenhoff spin fluid accretion tori around Kerr black holes
Sergio Gimeno-Soler, Sayantani Lahiri, Claus Lämmerzahl
The construction of equilibrium models of accretion disks around compact objects has become a highly relevant topic in the recent times, thanks to the current understanding that in…

Magnetized tori with magnetic polarization around Kerr black holes: Variable angular momentum discs
Sergio Gimeno-Soler, Oscar. M. Pimentel, Fabio D. Lora-Clavijo +2
Analytical models of magnetized, geometrically thick disks are relevant to understand the physical conditions of plasma around compact objects and to explore its emitting propertie…
