Quasar winds in galaxy evolution and accretion physics

点击翻译按钮获取中文摘要

Supermassive black holes are not independent entities, but grow as luminous quasars during an epoch when their host galaxies are also forming the bulk of their stars. The beautiful empirical correlations found between host galaxy properties and black hole masses indicate a relationship between these evolutionary events. It is remarkable that these two phenomena are linked at all; the black hole sphere of influence is on scales of parsecs while galaxies are measured in units a thousand times larger. As the growth of supermassive black holes cannot be fully understood independent of the evolution of their host galaxies, my overall research program focuses on the intersection of these phenomena. I am addressing this cosmological issue with the following projects:
