Here you can find a few visualizations of black holes and accretion disks based on numerical simulations.
Turning images of black holes into "v.Strokes" paintings
Author: Monika Moscibrodzka
Left panel (top and bottom): model image of a black hole generated by light ray-tracing through plasma falling onto the black hole.
The plasma model is based on supercomputer simulations of general relativistic magnetohydrodynamics.
Here the colors code the light intensity (red/brighter being more intense and blue/dimmer less intense).
Right panel (top and bottom): the same image as in the left but here the image is blured with a brush strokes. The direction of each
brush stroke is perpendicular to the local light polarization plane. What does this mean? This means that the brush strokes follow the
magnetic field structure responsible for the visible emission. In sum: left panel shows intensity of light and
right panel shows intensity of light and magnetic field lines producing it. Method used to create brush strokes is
called Line Integral Convolution (Carbal & Leedom 1993). Codes used to generate these
visualizations: ipole (Moscibrodzka & Gammie 2018)
and ipole-lic (Moscibrodzka 2020). These visualisations are nicknamed "v. Strokes" because they resemble v. Gogh paitings style.
Here is another version of the same visualization

Orbiting around supermassive black hole
Movie
Click on the slide above to see how accreting black hole
looks like for an observer that is orbiting around the black hole
being embedded in accretion disk. The observer orbit is shown in the
left panel in the figure above. This movie is based on
state-of-the-art general relativistic MHD simulations combined
with relativistic radiative transfer model.
Model of a Jet in M87 Galaxy
A model of relativistic jet in M87 galaxy seen at a various viewing angles.
Effects of relativistic abberation (beaming of light towards the direction of motion) can be clearly seen.
