摘要: Near-infrared and optical colour gradients of the discs non-active active spiral galaxies are investigated by using disc scalelengths. The measurements indicate that for JHK′ small no significant differences exist between galaxies. This result is different from what found wavelength regions, where observed in galaxies, but not ones. indicates do near-infrared.
