BH wake evolution in Run0. The gas density is projected over a width of 5 pc at times t = 30 (top left), 85 (top right), and 120 (bottom left) Myr for the supersonic regime, and 265 Myr (bottom right) for the transonic regime. Images are displayed along the velocity vector of the BH (Ur). The cross marks the BH position, the circle shows the size of the BHL radius, and the length of the black arrow is proportional to the BH velocity. The images are oriented such that the BH velocity vector, and hence the gas wake as well, is contained in the plane of the image, with the gas wake on the left-hand side of the BH position.
