Do Nuclear Star Clusters and Supermassive Black Holes Follow the Same Host-Galaxy Correlations?
Figure 2
(a): SMBH mass (red: elliptical galaxies, blue: disk galaxies) versus total galaxy stellar mass. (b): SMBH mass versus bulge stellar mass. (Data and sources in Table 1). The diagonal dashed lines are the best fits to the relation for the whole sample (black), for the elliptical galaxies (red), and for bulges of the disk galaxies (blue). Open symbols are galaxies without precise distances, which are not used in the fits. It is clear that the SMBH masses of S0 and spiral galaxies (blue) correlate better with the bulge stellar mass than with total galaxy mass.
