Add to ORKGWe 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
We examine under which conditions one may apply, to steady state keplerian accretion discs, the "bet...
