Normalised medians of MC properties (log scales) as a function of time. The properties shown are radius (R), velocity dispersion (σ_v), molecular gas mass (M), virial parameter (α_vir), surface mass density (Σ), and luminosity (L). The count refers to the total number of clouds in a time bin. The normalisation process included subtracting the initial value (first bin) of the property from it, and this was followed by a min-max standardisation. The symbols on the top represent the times at which outflows, photoionisation radiation, stellar winds, and supernovae begin in the simulation.
