Resolved JWST photometry reveals negative color gradients in three of four z>3 massive quiescent galaxies, and an age-only interpretation of these gradients eases—but does not remove—tensions with early-galaxy formation models.
PHAST data yield spatially resolved SFHs across M31's southern disk showing a global recent SFR decline driven by reduced ring activity, with mean rates of 0.445 and 0.285 solar masses per year over the last 100 and 20 Myr.
