The existence of sterile neutrino halos in galactic centers as an explanation of the black hole mass-velocity dispersion relation.

CHAN M.H. and CHU M.-C.

Abstract (from CDS):

If sterile neutrinos exist and form halos in galactic centers, they can give rise to observational consequences. In particular, the sterile neutrinos decay radiatively and heat up the gas in the protogalaxy to achieve hydrostatic equilibrium, and they provide the mass to form supermassive black holes (BHs). A natural correlation between the BH mass and velocity dispersion thus arises: log(MBH,f/M☉) = αlog(σ/200 km/s) + β with α ~ 4 and β ~ 8.
