IRS spectra of two ultraluminous infrared galaxies at z=1.3
V. Desai, L. Armus, B. T. Soifer +15
We present low-resolution (64 < R < 124) mid-infrared (8--38 micron) Spitzer/IRS spectra of two z~1.3 ultraluminous infrared galaxies (LFIR~10^13) discovered in a Spitzer/MIPS surv…
First Detection of PAHs and Warm Molecular Hydrogen in Tidal Dwarf Galaxies
S. J. U. Higdon, J. L. Higdon, J. Marshall
We observed two faint tidal dwarf galaxies (TDGs), NGC 5291N and NGC 5291 S with the Infrared Spectrograph on the Spitzer Space Telescope. We detect strong polycyclic aromatic hydr…
Detection of the Buried AGN in NGC 6240 with the Infrared Spectrograph on The Spitzer Space Telescope
L. Armus, J. Bernard-Salas, H. W. W. Spoon +10
We present mid-infrared spectra of the nearby, Ultraluminous Infrared Galaxy NGC 6240 taken with the IRS on Spitzer. The spectrum of NGC 6240 is dominated by strong fine-structure…
Redshifts from Spitzer Spectra for Optically Faint, Radio Selected Infrared Sources
D. W. Weedman, E. Le Floc'h, S. J. U. Higdon +2
Spectra have been obtained with the Infrared Spectrograph on the Spitzer Space Telescope for 18 optically faint sources (R > 23.9,mag) having f(nu) (24um) > 1.0,mJy and having radi…
The 1<z<5 Infrared Luminosity Function of Type I Quasars
Michael J. I. Brown, Kate Brand, Arjun Dey +14
We determine the rest-frame 8 micron luminosity function of type I quasars over the redshift range 1<z<5. Our sample consists of 292 24 micron sources brighter than 1 mJy selected…
Identifying silicate-absorbed ULIRGs at z~1-2 in the Bootes Field using Spitzer/IRS
M. M. Kasliwal, V. Charmandaris, D. Weedman +5
Using the 16m peakup imager on the Infrared Spectrograph (IRS) on Spitzer, we present a serendipitous survey of 0.0392 deg within the area of the NOAO Deep Wide Field Surv…
