Understanding the Role of Quasar Feedback in Galaxy Evolution Across and Luminosities and Redshifts

Observational evidence suggests that quasar activity plays an important role in regulating how galaxies and their nuclear supermassive black holes grow and co-evolve, despite their orders-of-magnitude difference in scale. In this talk, I will present a population of highly luminous dust-reddened quasars that may be the key to understanding this co-evolution. Red quasars are among the most intrinsically-luminous quasars in the Universe representing a short-lived phase in the lifetime of a quasar, during which their energy output (feedback) irrevocably impacts their host galaxies. I will present findings from several surveys that are uncovering this elusive population of quasars using various selection methods across the electromagnetic spectrum to probe a broad range of redshift and luminosity regimes. I will present results from detailed studies of selected subsamples that are beginning to shed light on the physics of feedback from quasars. I will discuss how reddened quasars fit into the larger picture of galaxy evolution which includes both mergers and secular growth.
