Evolution with redshift of 5 main timescales for regulating the growth of disk galaxies which lie along the star-forming galaxy main sequence shown for a range of redshift bins. The legend in the lower right panel gives the stellar mass value for each curve in the panels. Upper left: orbital timescale, t_orb. Upper centre: characteristic cooling timescale, t_cool. Upper right: fragmentation timescale of the gas, t_frag. Lower left: gas disruption timescale, t_disrupt. Lower left: gas depletion timescale, t_sfg.
