Description
The bulge contribution to the inner density profile of a galaxy is well
traced by the bulge's NIR surface brightness profile. We map the surface
brightness profiles of bulges using HST/NICMOS imaging. Most bulges show
nuclear components of 20-200 pc scales, and frequently also unresolved
nuclear star clusters (<20 pc). These nuclear components are the
densest parts of bulges, and gave bulges the “reputation” of
having high stellar concentration. Actually, the Sérsic
r1/n bulges typically have low concentrations, 1
