Evolution of the log ΣSFR–log ﹩{{\rm{\Sigma }}}_{{M}_{\ast }}﹩correlation over the past Gyr for three galaxies (UVCANDELS IDs 08062, 20524, 25207). log ΣSFR and log ﹩{{\rm{\Sigma }}}_{{M}_{\ast }}﹩are measured at the time of observation (cyan) and 1 Gyr lookback time (black), with correlation lines fit in the left panel for each galaxy. We also compute properties at 250, 500, and 750 Myr lookback time and trace the evolution of each region in log ΣSFR–log ﹩{{\rm{\Sigma }}}_{{M}_{\ast }}﹩space in the right panel. Inset F435W images of each galaxy are shown for reference. Galaxies 08062 and 20524, which have fewer regions than 25207, exhibit more stochastic evolutionary trajectories.
