- Simulation with high dynamic range (1E7) down to 0.1pc, i.e. to the accretion disk of a SMBH.
- Global instabilities make things quasi-stable locally due to turbulence.
- An exponential density profile for the gas in a disk arises naturally due to this.

- They say they cannot “rule out” gas accretion, but I wonder where the dividing line goes between a gas-rich dwarf being eaten and infall of gas.

- Black Hole – bulge mass relation
- They find that the direct accretion of cold gas during starbursts is an important growth mechanism for lower mass black holes and at high redshift. On the other hand, the re-assembly of pre-existing black hole mass into larger units via merging dominates the growth of more massive black holes at low redshift.
- As redshift decreases, progressively less massive black holes have the highest fractional growth rates, in line with recent claims of “downsizing” in quasar activity.

- Dwarf galaxies: correlations between their global stellar and dynamical properties, such as circular velocity, mass-to-light ratio, stellar mass, surface brightness, and metallicity.
- low and high z
- simulation work
- SN winds vs. ineficient SF
- useful to compare to where our data fall on these correlations
