Luminosities of L(CII) versus E(turb) for different types of galaxies. Here, the different behavior of SB and AGN galaxies is evident. SB galaxies have a greater potential for dissipating turbulent energy, and therefore, the calculated luminosities tend to dominate those of AGN. The shallower slope in SB galaxies suggests a nonlinear or less direct correlation between turbulent energy and emission, likely because other physical parameters – such as gas density, radiation field strength, or geometry – dominate the regulation of luminosity. The slope of the dependence for AGN, on the other hand, is steeper, indicating a more direct proportionality between turbulence energy input and [CII] luminosity, suggesting that confounding factors are less dominant.
