Gaseous and stellar column density maps in a 100 co-moving kpc box around the target galaxy at z ≈ 9.7, 8.3, 7.9 from left to right and from top to bottom. The middle panels show the disruption of the gaseous disc, which is absent in the stellar counterpart. The outward expanding bubble of less dense material, with its centre located at the same position of the central MBH, suggests a MBH-driven origin.
