Millimeter-Wave Spectroscopy and Mapping of Quasar Hosts, and the Status of ULIRGs as Quasar 2s
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.
