Black Hole Scaling Relations It has been over a decade since the discovery that the mass of a central black hole scales with the properties of its host galaxy. Because of these remarkable scaling relations, the idea that galaxies and black holes coevolve through some sort of self-regulated feedback has come to dominate scientific discussion. But do we really understand what the scaling relations are telling us? Since the original scaling measurements, the total number of supermassive black holes with direct mass measurements has reached 50. I will present recent developments from the observational perspective of the black hole scaling relations and how well coevolution models can handle this. In addition to coevolution, the scaling relations in the local universe inform the study of formation of black hole seeds, black hole density functions across cosmic time, and the disputed claims of evolution of the scaling relations with redshift. I will also explore what important, observational questions still need to be answered. University of Michigan host: Karl Gebhardt |
