COLIBRE hydrodynamical simulations reproduce observed HI and H2 Kennicutt-Schmidt relations at z~0 and predict H2 depletion time drops by a factor of ~20 from z=0 to z=8 due to falling metallicity, matching observations to z=5.
Below that surface density, m5 displays the steepest relationship (at 0≲log 10 (ΣHI/M⊙ pc−2)≲1)
