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…
Magnetized accretion disks around Kerr black holes with scalar hair -- Nonconstant angular momentum disks
Sergio Gimeno-Soler, José A. Font, Carlos Herdeiro +1
We present new equilibrium solutions of stationary models of magnetized thick disks (or tori) around Kerr black holes with synchronised scalar hair. The models reported here largel…
Magnetized discs and photon rings around Yukawa-like black holes
Alejandro Cruz-Osorio, Sergio Gimeno-Soler, José A. Font +2
We present stationary solutions of geometrically thick discs (or tori) endowed with a self-consistent toroidal magnetic field distribution surrounding a non-rotating black hole in…
Stationary models of magnetized viscous tori around a Schwarzschild black hole
Sayantani Lahiri, Sergio Gimeno-Soler, José A. Font +1
We present stationary solutions of magnetized, viscous thick accretion disks around a Schwarzschild black hole. We assume that the tori are not self-gravitating, are endowed with a…
Non-linear evolutions of magnetised thick discs around black holes: dependence on the initial data
Alejandro Cruz-Osorio, Sergio Gimeno-Soler, José A. Font
We build equilibrium solutions of magnetised thick discs around a highly spinning Kerr black hole and evolve these initial data up to a final time of about 100 orbital periods. The…
Self-gravitating magnetised tori around black holes in general relativity
Patryk Mach, Sergio Gimeno-Soler, Jose A. Font +2
We investigate stationary, self-gravitating, magnetised disks (or tori) around black holes. The models are obtained by numerically solving the coupled system of the Einstein equati…
Magnetized accretion disks around Kerr black holes with scalar hair - I. Constant angular momentum disks
Sergio Gimeno-Soler, José A. Font, Carlos Herdeiro +1
Testing the true nature of black holes - the no-hair hypothesis - will become increasingly more precise in the next few years as new observational data is collected in both the gra…
Magnetised Polish doughnuts revisited
Sergio Gimeno-Soler, José A. Font
We discuss a procedure to build new sequences of magnetised, equilibrium tori around Kerr black holes which combines two approaches previously considered in the literature. For sim…
