The [CII]-to-molecular gas conversion factor evolves from over 10,000 to about 10 solar masses per solar luminosity as galaxies enrich from very low metallicity at high redshift to higher values later, making a redshift-independent factor unusable.

SFUMATO# implements GPU-accelerated AMR for self-gravitational radiation hydrodynamics with new linearized implicit solvers for non-equilibrium chemistry and thermal evolution including dust.
Simulations match observed outflow masses within 0.5 dex but underpredict velocities by an order of magnitude and show face-on galaxies 15-40% more likely to exhibit detectable outflows than edge-on systems.
Star formation model choice in galaxy simulations controls giant molecular cloud lifetimes, yielding 20-30 Myr with sink particles versus over 200 Myr with the gravo-thermo-turbulent prescription.
