Do Nuclear Star Clusters and Supermassive Black Holes Follow the Same Host-Galaxy Correlations?
Peter Erwin, Dimitri Gadotti
TL;DR
This paper investigates whether nuclear star clusters and supermassive black holes follow similar host-galaxy correlations, finding that SMBHs correlate with bulge mass while nuclear clusters correlate with total galaxy mass, challenging the idea of a universal correlation.
Contribution
The study clarifies that nuclear star clusters and SMBHs have different host-galaxy correlations, emphasizing the importance of galaxy component distinctions.
Findings
SMBHs correlate with bulge stellar mass
Nuclear star clusters correlate with total galaxy stellar mass
No universal 'central massive object' correlation
Abstract
Recent studies have suggested a strong correlation between the masses of nuclear star clusters and their host galaxies, an extension of the known correlations between supermassive black holes (SMBHs) and their host galaxies. By focusing on disk galaxies with well-determined black hole and nuclear cluster masses, we argue that there is not a universal "central massive object" correlation after all: careful analysis shows that while SMBHs correlate better with the stellar masses of the bulge components, nuclear star clusters clearly correlate better with total galaxy stellar mass.
