Abstract: Surface Brightness Fluctuations (SBF) magnitudes have been proved as a potential tool for the study of composite stellar populations in galaxies. In particular, we focus on the detection of metal-poor secondary components in metal-rich dominated early type galaxies. Our current work consists in studying radial profiles of SBFs, hence we study the necessary conditions for the detection of SBF gradients. We show how the detection of SBF radial profiles is possible and its relation with the spatial distribution of the metal-poor small populations. In this manner, we can address how fast the chemical enrichment took place and describe the build up of the galaxy.
