Origin of correlations between central black-hole masses and Galactic bulge velocity dispersions
Abstract:We argue that the observed correlations between central black-hole masses MBH and Galactic bulge velocity dispersions e in the form MBH ∝ e4 may witness the pre-Galactic origin of massive black holes. Primordial black holes would be the centres for growing protogalaxies which experienced multiple mergers with ordinary galaxies. This process is accompanied by the merging of black holes in the galactic nuclei.
