This is my first test for accreting black hole in Blender Cycles (2.79) and Blender Eevee (2.8). For black hole I used glass shader with IOR based on layer weight (facing) in Cycles. In case of Eevee, I also used same same material but with blend mode ‘Alpha Hashed’. For accretion disk, I used concentric annulus circles because in reality each annulus circle rotates with different velocity (i.e. faster near to the black hole and slower far from the black hole). Accretion disk shader had noise texture with spherical gradient texture . If you have any query or suggestion, please let me know and all blend files available in video description.
Have fun :)
