Intermediate-Mass Black Holes

Jay Strader, Jenny E. Greene, Luis C. Ho

Dynamical and accretion signatures indicate that most galaxies with masses 10^9 to 10^10 solar masses contain black holes below 10^5 solar masses, while no solid detections exist in globular clusters.

Claims

C1strongest claim

We find that dynamical and accretion signatures alike point to a high fraction of 10^9-10^10 M_sun galaxies hosting black holes with M_BH<10^5 M_sun. In contrast, there are no solid detections of black holes in globular clusters.

C2weakest assumption

The interpretation that non-detections in globular clusters reflect true absence rather than observational limits or selection effects, and that the observed scatter in the M_BH-sigma relation is driven by a broad range in black hole mass and occupation fraction.

C3one line summary

A literature review finds that a high fraction of low-mass galaxies host intermediate-mass black holes below 100,000 solar masses, with no solid detections in globular clusters and the black hole mass-stellar velocity dispersion relation extending unbroken to lower masses despite large scatter.
