Median density profile of the five most massive gas clumps in each simulation (excluding the central 2 kpc of the galaxies, where radial inflows at galactic scale play a non-negligible role in the accumulation of gas). The top panel shows the radial profiles with the maximum density as the center, and the bottom panel those centered on the center of mass. The shaded areas show the robust standard deviation over these 5 clumps. The dashed line represents a power-law of index −2, for reference.
