Temporal evolution of the global fraction of turbulent energy in converging and diverging flows (blue curve) and in only converging (i.e., only cells with ∇ · v < 0; red curve) flows for three galaxies from our suite. The vertical black line indicates the moment of the blue nugget phase in each galaxy (Lapiner et al. 2023). The horizontal solid (dashed) lines indicate one third (sixth) of the total energy, values expected for fully isotropic and homogeneous turbulence in equipartition. Each of the blue nugget phases are preceded by at least one major merger, which increases the global fraction in compressive turbulence, before settling back to the equilibrium values.
