Coevolution of Black Holes and Galaxies: Recent Developments


I will review observational progress in defining and refining the various empirical scaling relations between black hole masses and host galaxy properties. I will emphasize ways in which the intrinsic scatter can be quantified, and present evidence that the scatter correlates with physical properties. I will discuss how to extend the scaling relations to active galaxies, and summarize preliminary efforts to probe the evolution of these scaling relations with redshift. I will present new measuremnts of the cold ISM content in AGN host galaxies, and constraints they place on currently popular models of AGN feedback. Lastly, I will discuss a new class of low-mass black holes in bulgeless and dwarf galaxies that serve as local analogs of seed supermassive black holes.
