A Connection between Star Formation in Nuclear Rings and their Host Galaxies
Lisa M. Mazzuca, Johan H. Knapen, Sylvain Veilleux +1
We present results from a photometric H-alpha survey of 22 nuclear rings, aiming to provide insight into their star formation properties, including age distribution, dynamical time…
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…
The Oxygen Abundances of Luminous and Ultraluminous Infrared Galaxies
David S. N. Rupke, Sylvain Veilleux, Andrew J. Baker
Luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs) dominate the star formation rate budget of the universe at z > 1, yet no local measurements of their heavy element a…
Tracing PAHs and Warm Dust Emission in the Seyfert Galaxy NGC 1068
Justin H. Howell, Joseph M. Mazzarella, Ben H. P. Chan +16
We present a study of the nearby Seyfert galaxy NGC 1068 using mid- and far- infrared data acquired with the IRAC, IRS, and MIPS instruments aboard the Spitzer Space Telescope. 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…
