Mass-weighted stellar age (⟨a⟩_*^m) as a function of redshift (z), color-coded by the sSFR. Stars represent individual measurements for our sample, and the error bars represent the 1σ uncertainties. The dashed black line represents the best-fit power-law model for the entire galaxy sample. Comparative literature results for intermediate-z (Álvarez-Márquez et al. 2019; Shivaei et al. 2020a) and high-z objects (Witstok et al. 2023; Bunker et al. 2023; Markov et al. 2023; Ormerod et al. 2025) are depicted as gray symbols, with their respective 1σ uncertainties.
