Why Are Only High-Redshift Obscured AGN Bright Submillimeter Sources?,nosity . and the redshift of the absorbed QSOs. The FIR emission of these objects is due to dust heated by starbursts, rather than reprocessed QSO emission . The implied star formation rates (SFR) are >1000 M./y, sufficient to build a substantial fraction of a galaxy spheroid in only a few 100 Myr.

https://doi.org/10.1007/978-94-017-2660-3al black-holes comprise a larger fraction of the host galaxy mass at higher redshifts. In a scenario where quasars are triggered by halo mergers, this scaling, in combination with observed number counts imply that quasars have an episodic lifetime that is set by the dynamical time of a galactic disk rather than by the Salpeter time.
