M• − σrelation for intermediate-mass black holes in globular clusters

Context. For galaxies hosting supermassive black holes (SMBHs), it has been observed that the mass of the central black hole (M•) tightly correlates with the effective or central velocity dispersion (σ) of the host galaxy. The origin of this M• − σ scaling relation is assumed to lie in the merging history of the galaxies, but many open questions about its origin and the behavior in different mass ranges still need to be addressed.
