Blue Compact Dwarf Galaxies with Spitzer: The Infrared/Radio Properties
Yanling Wu, V. Charmandaris, J. R. Houck +4
We study the correlation between the radio, mid-infrared and far-infrared properties for a sample of 28 blue compact dwarf (BCD) and low metallicity star-forming galaxies observed…
Dust Properties and Star-Formation Rates in Star-Forming Dwarf Galaxies
J. L. Rosenberg, Yanling Wu, Emeric Le Floc'h +5
We have used the Spitzer Space Telescope to study the dust properties of a sample of star-forming dwarf galaxies. The differences in the mid-infrared spectral energy distributions…
Spitzer-IRS high resolution spectroscopy of the 12μm Seyfert galaxies: I. First results
Silvia Tommasin, Luigi Spinoglio, Matthew A. Malkan +3
The first high resolution Spitzer IRS 9-37um spectra of 29 Seyfert galaxies (about one quarter) of the 12um Active Galaxy Sample are presented and discussed. The high resolution sp…
Chemical composition and mixing in giant HII regions: NGC3603, 30Doradus, and N66
V. Lebouteiller, J. Bernard-Salas, B. Brandl +5
We investigate the chemical abundances of NGC3603 in the Milky Way, of 30Doradus in the Large Magellanic Cloud, and of N66 in the Small Magellanic Cloud. Mid-infrared observations…
Elemental Abundances of Blue Compact Dwarfs from mid-IR Spectroscopy with Spitzer
Yanling Wu, J. Bernard-Salas, V. Charmandaris +4
We present a study of elemental abundances in a sample of thirteen Blue Compact Dwarf (BCD) galaxies, using the 10--37m high resolution spectra obtained with Spitzer/IRS.…
Decomposing Dusty Galaxies. I. Multi-Component Spectral Energy Distribution Fitting
J. A. Marshall, T. L. Herter, L. Armus +4
We present a new multi-component spectral energy distribution (SED) decomposition method and use it to analyze the ultraviolet to millimeter wavelength SEDs of a sample of dusty in…
