Figure 1. Sizes in observed wavelengths of our sample galaxies are shown in grey points. The median values of each waveband are shown in larger black points. Empty symbols are previous measurements. On the top we show cutout images with from HST, Spitzer, and JWST of one of our sample galaxy, and these cutouts are aligned vertically roughly to the wavelengths shown in the x-axis below. Our results suggest that in the active formation phase massive galaxies form their masses in the central compact regions, although most of their masses are located in the outskirts, presumably formed in the previous formation episodes.
