Evolution of the class median d₅ parameter values (Remus & Kimmig 2025) across cosmic time. Lower values indicate a denser environment of a galaxy. We chose comoving coordinates for a better comparison between across cosmic time. The 50th percentile scatter range shown in gray in the bottom left corner is similar for all classes and cosmic cosmic time. All classes show a very similar evolution with only faint differences with main-sequence types residing in denser environments consistently and caught-types found in less dense environments.
