  "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 blackholes. A natural correlation between the blackhole mass and velocity dispersion thus arises $\\log(M_{BH,f}/M_{\\odot})=\\alpha \\log (\\sigma /200 {\\rm km s^{-1}})+ \\beta$ with $\\alpha \\approx 4$ and $\\beta \\approx 8$.",
