MAMBO 1.2mm observations of luminous starbursts at z~2 in the SWIRE fields
C. J. Lonsdale, M. Polletta, A. Omont +19
We report on--off pointed MAMBO observations at 1.2 mm of 61 Spitzer-selected star-forming galaxies from the SWIRE survey. The sources are selected on the basis of bright 24um flux…
From rings to bulges: evidence for rapid secular galaxy evolution at z~2 from integral field spectroscopy in the SINS survey
R. Genzel, A. Burkert, N. Bouche +22
We present Ha integral field spectroscopy of well resolved, UV/optically selected z~2 star-forming galaxies as part of the SINS survey with SINFONI on the ESO VLT. Our laser guide…
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…
Uncovering the Active Galactic Nuclei in Low-Ionization Nuclear Emission-Line Regions with Spitzer
David Rupke, Sylvain Veilleux, DongChan Kim +6
The impact of active galactic nuclei on low-ionization nuclear emission-line regions (LINERs) remains a vigorous field of study. We present preliminary results from a study of the…
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…
Dust covering factor, silicate emission and star formation in luminous QSOs
R. Maiolino, O. Shemmer, M. Imanishi +4
We present Spitzer IRS low resolution, mid-IR spectra of a sample of 25 high luminosity QSOs at 2<z<3.5. When combined with archival IRS observations of local, low luminosity type-…
