MBH-σ relation between supermassive black holes and the velocity dispersion of globular cluster systems.

SADOUN R. and COLIN J.

Abstract (from CDS):

We find evidence that the mass MBH of central supermassive black holes (SMBHs) correlates with the velocity dispersion σGCof globular cluster systems of their host galaxies. This extends the well-known MBHsph relation between black hole mass and velocity dispersion of the host spheroidal component. We compile published measurements of both MBH and σGCfor a sample of 13 systems and find the relation log (MBH) =α+βlog (σGC/200), with α= 8.63 ±0.09 and β= 3.76±0.52. We also consider blue (metal-poor) and red (metal-rich) globular cluster subpopulations separately and obtain a surprisingly tight correlation using only the velocity dispersion σGCred of the red clusters with α= 8.73±0.09 and β= 3.84±0.52 and an intrinsic scatter {Ux025b}0= 0.22 dex compared to {Ux025b}0= 0.27 dex for the MBHsph relation of our sample. We use this MBHsph relation to estimate the central black hole mass in five galaxies for which σGCred is measured. The sudden appearance of CO emission in LHA 115-S 65
