This process operates on timescales of only a few hundred Myr and persists even at late cosmic times. One prediction of this quasi-periodic, galactic-scale \"breathing\" is an $anti$-correlation between star formation rate (SFR) and half-light radius as central gas overdensities lead to starbursts whose feedback drags stars to larger radii while star formation dwindles.
