Context.The recent finding of substantial masses of cold molecular gas as well as young stellar populations in the host galaxies of intermediate luminosity quasars is at odds with results of Hubble Space Telescope imaging studies since the latter appear to yield mature, quiescent early type hosts.
Aims.The characterization as “quiescent” for the host galaxies of QSOs is being addressed.
Methods.The radio and far-infrared properties of both the HST sample and a larger comparison sample of uv-excess selected radio-quiet QSOs are being analyzed.
Results.Consistency is found with substantial recent or ongoing star-formation activity.
