Planetary Nebulae: Exposing the Top Polluters of the ISM
Joseph L. Hora, Massimo Marengo, Howard A. Smith +2
The high mass loss rates of stars in their asymptotic giant branch (AGB) stage of evolution is one of the most important pathways for mass return from stars to the ISM. In the plan…
Spitzer Mid-Infrared Spectroscopy of Distant X-ray Luminous AGN
Kate Brand, Dan W. Weedman, Vandana Desai +7
We present mid-infrared spectroscopy of a sample of 16 optically faint infrared luminous galaxies obtained with the Infrared Spectrograph (IRS) on the Spitzer Space Telescope. Thes…
High-excitation OH and H_2O lines in Markarian 231: the molecular signatures of compact far-infrared continuum sources
Eduardo González-Alfonso, Howard A. Smith, Matthew L. N. Ashby +3
The ISO/LWS far-infrared spectrum of the ultraluminous galaxy Mkn 231 shows OH and H_2O lines in absorption from energy levels up to 300 K above the ground state, and emission in t…
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…
Spitzer Mid-Infrared Spectroscopy of 70um-Selected Distant Luminous Infrared Galaxies
Kate Brand, Dan W. Weedman, Vandana Desai +7
We present mid-infrared spectroscopy obtained with the Spitzer Space Telescope of a sample of 11 optically faint, infrared luminous galaxies selected from a Spitzer MIPS 70um imagi…
Point Sources from a Spitzer IRAC Survey of the Galactic Center
Solange V. Ramirez, Richard G. Arendt, Kris Sellgren +4
We have obtained Spitzer/IRAC observations of the central 2.0 x 1.4 degrees (~280 x 200 pc) of the Galaxy at 3.6-8.0 microns. A point source catalog of 1,065,565 objects is present…
