Dust mass at the time of observation divided by the dust mass of MS galaxies at the time of quenching as a function of time since quenching for three different bins of quenching redshift (green filled symbols). The empty symbols show the upper limits when assuming a lower dust temperature of 17 K. The yellow, orange-hatched, and red-chequered regions show the dust removal timescales from Michałowski et al. (2019, τ = 2.5 ± 0.4 Gyr), Leśniewska et al. (2023, τ = 2.26 ± 0.18 Gyr), and Nadolny et al. (2024, τ = 2.28 ± 0.1 Gyr), for three different fractional initial gas fractions (f_0, gas). The empty purple symbol marks the f_0, gas from the fit of Gobat et al. (2020). Light blue and dark blue symbols show dust mass evolution with time since quenching from Donevski et al. (2023) for spiral and elliptical QGs at z < 0.7, respectively, where we assume a 30% error on the dust mass, and the horizontal error bars denote the bin size of Donevski et al. (2023).
