Median quenching timescales as a function of stellar metallicity (top) and formation redshift (bottom) for the quiescent galaxy population. We separated the data into four size bins: Δlog(R_e)≤ − 0.23, −0.23 < Δlog(R_e) < 0, 0 < Δlog(R_e) < 0.23, and Δlog(R_e)≥0.23. The larger circles correspond to larger galaxies. The yellow square marks the median value measured for the PSB population. The error bars indicate the statistical uncertainty on the median ($\sigma /\sqrt{N}$). The larger quiescent galaxies quench more slowly, tend to be marginally younger, and have near-solar metallicities. The compact quiescent galaxies are found to be metal-rich and seem to follow two distinct quenching pathways, one characterized by early and moderately fast quenching (⟨τ_q⟩ = 0.8 Gyr), and another characterized by late and rapid (⟨τ_q⟩ = 0.13 Gyr) quenching.
