Abstract

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☉) = α log(σ/200 km s⁻¹) + β with α ≈ 4 and β ≈ 8. Copyright © 2009 The American Astronomical Society.
