Evolution of the molecular fraction, where the formation of H2 has been suppressed for gas denser than a fixed threshold. The top panel corresponds to the standard case, with no suppression of H2 formation. The middle panel shows the evolution for a density threshold of n = 1000 [ cm-3 ], while the bottom panel corresponds to a density threshold of n = 100 [ cm-3 ]
