Star formation in the hosts of high-z QSOs: Evidence from Spitzer PAH detections
D. Lutz, E. Sturm, L. J. Tacconi +7
We present Spitzer rest-frame mid-infrared spectroscopy of twelve z~2 mm-bright type 1 QSOs, selected from unlensed and lensed QSO samples and covering a range of AGN optical lumin…
Extended silicate dust emission in PG QSOs
M. Schweitzer, B. Groves, H. Netzer +9
This paper addresses the origin of the silicate emission observed in PG QSOs, based on observations with the Spitzer Space Telescope. Scenarios based on the unified model suggest t…
Spitzer Quasar and ULIRG Evolution Study (QUEST): II. The Spectral Energy Distributions of Palomar-Green Quasars
Hagai Netzer, Dieter Lutz, Mario Schweitzer +10
This is the second paper studying the QSOs in the spitzer QUEST sample. Previously we presented new PAH measurements and argued that most of the observed far infrared (FIR) radiati…
PAH emission and star formation in the host of the z~2.56 Cloverleaf QSO
D. Lutz, E. Sturm, L. J. Tacconi +7
We report the first detection of the 6.2micron and 7.7micron infrared `PAH' emission features in the spectrum of a high redshift QSO, from the Spitzer-IRS spectrum of the Cloverlea…
Host dynamics and origin of Palomar-Green QSOs
K. M. Dasyra, L. J. Tacconi, R. I. Davies +7
We present host-galaxy velocity dispersions of 12 local (mainly Palomar-Green) quasi-stellar objects (QSOs) measured directly from the stellar CO absorption features in the H band.…
Spitzer Quasar and ULIRG evolution study (QUEST): I. The origin of the far infrared continuum of QSOs
M. Schweitzer, D. Lutz, E. Sturm +13
This paper addresses the origin of the far-infrared (FIR) continuum of QSOs, based on the Quasar and ULIRG Evolution Study (QUEST) of nearby QSOs and ULIRGs using observations with…
