GRMHD simulations of accretion onto a black hole
Movies
Some movies made from the 2-D simulations (no significant differences were found in 3-D simulations):
Lorentz factor
Accretion onto rapid rotating black hole
Accretion onto extreme rotating black hole
Density
Accretion onto rapid rotating black hole
Accretion onto extreme rotating black hole
The radial extent of the simulation is 700M (2M is the Schwarzschild radius).
The density is relative to the maximum density in the initial torus surrounding the black hole. NOTE that along the rotational axis (the funnel), the density is very low.
