SFR histories for five representative galaxies from the NIHAO simulation suite, sorted in descending order by their stellar mass. Each panel displays the SFR as a function of lookback time for an individual system. Header labels indicate the galaxy identifier, stellar mass, bursty mass fraction, and the mass ratio M_★,post/M_★,pre (refer to Sec. 3.1 and 3.2). The grey shaded region denotes z> 6.5, representing the re-ionisation epoch limit. SFRs are calculated using two sliding temporal windows: 0.5 Gyr (orange) and 0.05 Gyr (blue). A dashed green line indicates a burst threshold, defined as 1.5 times the 0.5 Gyr averaged SFR. High-cadence SFR segments exceeding this threshold are highlighted in dark blue, while light red shaded regions indicate the identified SFR burst intervals.
