Top panels: Distributions of the number of rejuvenation episodes, of the SFR during each episode, and of the associated timescale. Bottom panels: Distributions of the total number of mergers in the last snapshot just before the rejuvenation episodes, of the number of mergers with a mass ratio of at least 1/10, and of the associated fractional increase of stellar mass (excluding the stellar mass that is accreted through mergers). Magenta and cyan are for the 15th and 85th percentiles of the o3 distributions.
