Evolution of the characteristic timescale for star formation as a function of the redshift. Left: τs for different IMF exponent and the evolution of the dynamical time (tdyn), taken to be 10% of Hubble time. Right: our results compared with the timescales for the conversion of gas (filled areas) obtained by Péroux & Howk (2020) and Maio et al. (2022) for molecular and cold (HI + H2) gas.
