Dark matter does not act as growth factor

(PhysOrg.com) -- Massive black holes have been found at the centers of almost all galaxies, where the largest galaxies – which are also the ones embedded in the largest halos of Dark Matter – harbor the most massive black holes. This has led to speculation that there is a direct link between Dark Matter and black holes, i.e. that exotic physics controls the growth of black holes. Scientists at the Max Planck Institute of Extraterrestrial Physics, the University Observatory Munich and the University of Texas in Austin conducted an extensive study of galaxies to prove that black hole mass is not directly related to the mass of the Dark Matter halo but rather appears to be determined by the formation of the galaxy bulge.
