Descripción
By combining surface brightness profiles from images taken in the
HST/NICMOS F160W and ground-based K bands, we have obtained NIR profiles
for a well studied sample of inclined disk galaxies, spanning radial
ranges from 20 pc to a few kpc. We fit PSF-convolved
Sersic-plus-exponential laws to the profiles, and compare the results
with the fits to the ground-based data alone. HST profiles show light
excesses over the best-fit Sersic law in the inner sim1 arcsec. This is
often as a result of inner power-law cusps similar to the inner profiles
of intermediate-luminosity elliptical galaxies.
