HST Morphologies of z~2 Dust Obscured Galaxies I: Power-law Sources
R. S. Bussmann, Arjun Dey, J. Lotz +12
We present high spatial resolution optical and near-infrared imaging obtained using the ACS, WFPC2 and NICMOS cameras aboard the Hubble Space Telescope of 31 24um--bright z~2 Dust…
Radio and Infrared Selected Optically Invisible Sources in the Boötes NDWFS
J. L. Higdon, S. J. U. Higdon, S. P. Willner +4
We have combined data from the NOAO Deep Wide-Field Survey in Bootes and the Spitzer Space Telescope to determine basic properties for sixteen optically "invisible" MIPS 24um (OIMS…
A Significant Population of Very Luminous Dust-Obscured Galaxies at Redshift z ~ 2
Arjun Dey, B. T. Soifer, Vandana Desai +12
Observations with Spitzer Space Telescope have recently revealed a significant population of high-redshift z~2 dust-obscured galaxies (DOGs) with large mid-IR to UV luminosity rati…
Spitzer Observations of Tidal Dwarf Galaxies
Sarah J. U. Higdon, James L. Higdon
We present Spitzer observations of Tidal Dwarf Galaxies (TDGs) in three interacting systems: NGC 5291, Arp105 and Stephan's Quintet. The spectra show bright emission from polyaroma…
High resolution mid-infrared spectroscopy of ultraluminous infrared galaxies
D. Farrah, J. Bernard-Salas, H. W. W. Spoon +8
(Abridged) We present R~600, 10-37um spectra of 53 ULIRGs at z<0.32, taken using the IRS on board Spitzer. All of the spectra show fine structure emission lines of Ne, O, S, Si and…
Optical Line Diagnostics of z~2 Optically Faint ULIRGs in the Spitzer Bootes Survey
K. Brand, A. Dey, V. Desai +9
We present near-infrared spectroscopic observations for a sample of ten optically faint luminous infrared galaxies (R-[24]> 14) using Keck NIRSPEC and Gemini NIRI. The sample is se…
