Star-forming QSO host galaxies

Abstract

The recent finding of substantial masses of cold molecular gas as well as young stellar populations in the host galaxies of quasars is at odds with results of Hubble Space Telescope imaging studies, since the latter appear to yield mature, quiescent early type hosts. It is demonstrated here that the characterization as `quiescent' is incorrect. Radio and far-infrared properties of both the HST sample and a larger comparison sample of uv-excess selected radio-quiet QSOs are consistent with substantial recent star-formation activity.
