The masses of supermassive black holes are known to correlate with theproperties of the bulge components of their host galaxies. In contrast, theyappear not to correlate with galaxy disks. Disk-grown pseudobulges areintermediate in properties between bulges and disks. It has been unclearwhether they do or do not correlate with black holes in the same way thatbulges do, because too few pseudobulges were classified to provide a clearresult. At stake are conclusions about which parts of galaxies coevolve withblack holes, possibly by being regulated by energy feedback from black holes.Here we report pseudobulge classifications for galaxies with dynamicallydetected black holes and combine them with recent measurements of velocitydispersions in the biggest bulgeless galaxies. These data confirm that blackholes do not correlate with disks and show that they correlate little or not atall with pseudobulges. We suggest that there are two different modes of blackhole feeding. Black holes in bulges grow rapidly to high masses when mergersdrive gas infall that feeds quasar-like events. In contrast, small black holesin bulgeless galaxies and galaxies with pseudobulges grow as low-levelSeyferts. Growth of the former is driven by global processes, so the biggestblack holes coevolve with bulges, but growth of the latter is driven locallyand stochastically, and they do not coevolve with disks and pseudobulges.

Supermassive black holes do not correlate with galaxy disks or pseudobulges
