• 2D simulation of an accretion disk with jet

    Ever watched a black hole launch matter into space? Me neither, but this simulation comes pretty close! The video below is a visualization of a high resolution 2D simulation of the accretion disk of a black hole, made by me using the state-of-the-art GRMHD* code called HAMR** on a single GPU. The simulations are partly refined to give an effective resolution of 600×600 pixels. Units are in terms of Rg (gravitational radius), so the simulation applies to any black hole mass. The accretion disk starts out with a poloidal magnetic flux, which powers the jet once the accretion starts. The left plot shows the density distribution, clearly visualizing the accretion…
