Investigating the delay between dust radiation and star-formation in local and distant quenching galaxies

We investigate the timescale with which IR luminosity decreases after a complete and rapid quenching of star formation using observations local high-redshift galaxies. From SED modelling, we derive time since subsample 14 galaxies from Herschel Reference Survey suffering ram-pressure stripping due to environment Virgo cluster 7 rapidly quenched COSMOS selected through state-of-the-art statistical method already tested on determination galaxies' history. Three out have an optical spectra no emission line, confirming their nature. Present physical properties two samples are obtained as well past L$_{IR}$ these galaxies, just before quenching, long-term SFH properties. This is shown be consistent reference normally star-forming same $M_*$ $z$ than each our put constraints present ratio function time. The probe different dynamical ranges in terms age HRS exhibiting longer timescales (0.2-3\,Gyr) compared one ($<100$\,Myr). Assuming exponential decrease short e-folding times less couple hundreds Myr while compatible several Myr. For sample, this result ram pressure environment. processes acting intermediate timescales. Processes such galaxy mergers, disk instabilities or environmental effects can produce strong variability.
