The Co‐Formation of Spheroids and Quasars Traced in their Clustering
The Co‐Formation of Spheroids and Quasars Traced in their Clustering
We compare observed clustering of quasars and galaxies as a function of redshift, mass, luminosity, and color/morphology, to constrain models of quasar fueling and the co-evolution of spheroids and supermassive black holes (BHs). High-redshift quasars are shown to be drawn from the progenitors of local early-type galaxies, with the characteristic …
