Mass-weighted distributions of gas radial velocity (upper panels) and density (middle panels) at t = 20 Myr, for the runs with (right-hand panels) and without radiative losses (left-hand panels). The distribution of metals in radial velocity bins at the same time for the two runs (lower panels) is also shown. The red (green) lines on the left (right) panels show all the gas and metals in the simulation volume. The yellow solid and blue dotted lines in all panels show the hot (T ≥ 10⁵ K) and cold/warm (T <  10⁵ K) components, respectively. The integrals of the red and green lines are normalized to unity.
