Multi-Wavelength Characterization of the Outskirts of Spiral Galaxies
We have explored late-type spiral galaxies with truncated radial surface brightness profiles. Based on the study of optical color profiles, [1] suggested that truncated (TYPE II) galaxies have a generally older stellar population in their outer regions: one observable consequence of this would be a strong dependence of the structural parameters of
