Description
We have analyzed the structure of bulges of early-to intermediate-type spirals, on nuclear and global scales, using HST NIR imaging together with ground-based NIR imaging. The goals are (a) to see whether results on bulge structure derived from ground-based, 1" FWHM seeing data remain valid when high-resolution HST data are used; (2) to compare nuclear properties of bulges to those of ellipticals; and (3) to provide bulge-disk scaling relations based on accurate profile decompositions employing the HST data. Details are presented in Balcells et al. (2003, 2004a, 2004b).
