Spitzer_Approved_Extragalactic Mar 25, 10 16:24 Page 547/742 Spitzer Space Telescope − General Observer Proposal #40001 The Origin of QSO Extended Emission Regions: Superwinds from Starbursts or QSO Ignition? Principal Investigator: Alan Stockton Institution: Institute for Astronomy, University of Hawaii Technical Contact: Alan Stockton, IfA, University of Hawaii Co−Investigators: Hai Fu, Institute for Astronomy, University of Hawaii Science Category: AGN/quasars/radio galaxies Observing Modes: IrsStare MipsPhot Hours Approved: 12.4 Abstract: Luminous, massive extended emission−line regions (EELRs) are found around a substantial fraction of low−redshift radio−loud QSOs. These EELRs typically extendfor several tens of kpc and are highly structured entities. In spite of their preference for radio−loud QSOs, they generally show no significant correlation with radio jets or lobes. They also show no tendancy to follow the morphology of the host galaxy. A number of lines of evidence indicate strongly that this gas has been ejected from the host galaxy by a powerful superwind, but whether this wind is due to a central starburst or to radiative coupling of the QSO’s energy output to surrounding dust and gas is uncertain. We propose spectroscopy of the 8 micron PAH feature with the IRS Low Res 7.4−14.5 micron module and MIPS 24, 70, and 160 micron photometry to constrain the star−formation rates in carefully matched samples of steep−spectrum, radio−loud QSOs with and without luminous EELRs.

It opens up an enormous amount of discovery space given the increased depth, improved resolution, and areal coverage that Spitzer provides. The extragalactic FLS team at the Spitzer Science Center has been involved in the planning of the survey since its inception and we have gathered a substantial ancillary data set, from optical through radio wavelengths, to maximize the science return of the survey. We have several science programs underway and a common feature to most is the need for photometric redshifts for the thousands of galaxies detected in the survey. We are requesting one year of funding for a post−doc to focus on this effort and we will return to the community via NED a database with the multiwavelength SEDs and photometric redshifts for the survey galaxies.

Do obscured (type II) quasars exist? If so, how many are there? To date, only a small number of candidates have been found. We recently published a sample of 150 type II quasar candidates at redshifts z
