Spins in galaxies of different morphologies as a function of MBH mass (mean and 1σ dispersion). Filled circles: gas-poor galaxies (spheroids). Stars: gas-rich galaxies (disks). Bottom: z < 0.5. Top: 0.5 < z < 1. Lower mass MBHs in gas-rich galaxies tend to spin less rapidly than higher mass MBHs and also less rapidly than MBHs in gas-poor galaxies.
