How important is the dark matter halo for black hole growth?

Understand

In this paper, we examine if the properties of central black holes in galactic nuclei correlate with their host dark matter halo.

• We analyze the entire sample of galaxies where black hole mass, velocity dispersion, sigma, and asymptotic circular velocity, Vc, have all been measured.
• We fit M-sigma and M-Vc to a power law, and find that in both relationships the scatter and slope are similar.
• This model-independent analysis suggests that although the black hole masses are not uniquely determined by dark matter halo mass, when considered for the current sample as a whole, the M-Vc correlation may be as strong (or as weak) as M-sigma.
