Particle density slices of a 10⁵ M_⊙ molecular cloud embedded in a 10⁵ K outflow. The left column shows the system’s state after 0.5 Myr, the right one – at t_frag. Outflow velocity (Mach number), indicated at the top left of each panel, increase from 10 km s⁻¹ (𝓜 = 0.21) in the top row to 400 km s⁻¹ (𝓜 = 8.56) in the bottom one. Coordinates are centred on the cloud centre of mass, with outflow velocity in the positive x direction.
