General Relativistic Magnetohydrodynamics (GRMHD) simulation of a black hole accretion disk and jet. The gas is orbiting around the central black hole and slowly moving toward it. The disk is highly turbulent and seeded with the entangled magnetic field lines, shown by the white lines. The jet structure is highlighted with the white contour surface. The disk is tenuous and would not be very luminous in the sky, which is a good model for Sgr A*, one of the main targets of the EHT. This simulation
