| Abstract: | It is becoming possible to detect high redshift quasars in various molecular lines, and to show by mapping lensed objects that the strong dust and molecular emission arises in warm dense ∼ 100 pc-scale “tori.” The properties of ULIRGS, at least those with AGN-like narrow line regions, are very similar, as expected in the hidden quasar hypothesis. Several of the latter are in fact confirmed as “Quasar 2s” by spectropolarimetry. I argue against claims that the source of the majority of the luminosity has been determined in any ULIRG or Scuba sources. |
