Assembly history for the virial mass (left), stellar mass (second left), and gas (third left) components along with the median sSFR evolution (rightmost panel). Virial and stellar masses are normalised to their values at z = 0, while the gas component is normalised to the stellar mass at z = 0 for each subsample. The values of sSFR are not normalised (right margin). It is important to notice that the scale is different among the panels, with the three leftmost using the linear scale at the left and the rightmost using the logarithmic scale at the right. Haloes grow at a similar pace between the samples, but stars and gas show clear differences. Spheroid-dominated galaxies assemble their stars and consume their gas at earlier times than disc-dominated objects. Our mostly-disc sample shows steady star formation over time, maintaining a richer gas supply and a more sustained star formation rate over time than the intermediate and spheroid-dominated sample.
