Binned r-band surface brightness profiles vs radius . Our sample is divided into six mass bins with intervals defined by log(M_*/ M_⊙) = 8.9,10.0, 10.3, 10.6, 10.8,11.0, and 11.3. In each panel, we bin the profiles of galaxies within a certain mass bin for cold (λ_z ≥ 0.8, blue lines), warm (0.25 < λ_z < 0.8, orange lines), and hot (λ_z ≤ 0.25, red lines) components separately. The number of galaxies N in each bin is shown by the text. The horizontal dotted lines in each panel represent the values of 10¹ and 10².
