The Central kpc of Galaxy Bulges
We study the innermost regions of bulges with surface-brightness data derived from combined HST/NICMOS and ground-based NIR profiles. Bulge profiles to 1--2 kpc may be fit with Sersic laws and show a trend with bulge-to-disk ratio: low-B/D bulges are roughly exponential, whereas higher-B/D bulges show increasing Sersic shape index, n, indicating
