Caption: Figure 10.

The projected radial profiles of galaxy 25207 have similar shapes across all properties. log ΣSFR, log sSFR, AV, and tx fractions show a steep decline from the galactic center, with contours tracing the underlying distribution of regions. This behavior appears both at the time of observation and 1 Gyr lookback time, indicating a galactic center that is old yet continuously star-forming.
