Luis C. Ho investigates supermassive black holes and their connections to host galaxies. His review with John Kormendy organized dynamically measured black hole masses by host structure, including classical bulges, galactic disks and pseudobulges.
The distinction changes the physical interpretation of a scaling relation. Strong correlations with some bulge properties do not establish equally close coupling to every component of a galaxy. The review argued that weak relations for galactic disks and pseudobulges require a richer account of black hole growth than a single universal coevolution rule.[ref]
