A Gravitational Instability-Driven Viscosity in Self-Gravitating Accretion Disks

Abstract

We derive a viscosity from gravitational instability in self-gravitating accretion disks, which has the required properties to account for the observed fast formation of the first super-massive black holes in highly redshifted quasars and for the cosmological evolution of the black hole-mass distribution.
