The nature of faint Spitzer-selected dust-obscured galaxies
Alexandra Pope, R. Shane Bussmann, Arjun Dey +12
We use deep far-IR, submm, radio and X-ray imaging and mid-IR spectroscopy to explore the nature of a sample of Spitzer-selected dust-obscured galaxies (DOGs) in GOODS-N. A sample…
Contribution to Unresolved Infrared Fluctuations from Dwarf Galaxies at Redshifts of 2-3
Ranga-Ram Chary, Asantha Cooray, Ian Sullivan
In order to understand the origin of clustered anisotropies detected in Spitzer images between 3.6 and 8 microns, we stack the Spitzer IRAC/Great Observatories Origins Deep Survey…
Spitzer Constraints on the z=6.56 Galaxy Lensed by Abell 370
Ranga-Ram Chary, Daniel Stern, Peter Eisenhardt
We report on Spitzer IRAC observations of the spectroscopically confirmed z=6.56 lensed Ly-alpha emitting source HCM 6A which was found behind the cluster Abell 370. Detection of t…
Spitzer Detection of PAH and Silicate Dust Features in the Mid-Infrared Spectra of z~2 Ultraluminous Infrared Galaxies
Lin Yan, R. Chary, L. Armus +6
We report the initial results from a Spitzer GO-1 program to obtain low resolution, mid-infrared spectra of infrared luminous galaxies at z~1-2. This paper presents the spectra of…
The Nature of Faint 24 micron Sources Seen in Spitzer Observations of ELAIS-N1
R. Chary, S. Casertano, M. E. Dickinson +7
The Spitzer Space Telescope has undertaken the deepest ever observations of the 24 micron sky in the ELAIS-N1 field as part of GOODS Science Verification observations. We present t…
Lower Mass Black Holes in the GOODS? Off-nuclear X-ray Sources
A. E. Hornschemeier, D. M. Alexander, F. E. Bauer +9
We have identified a sample of 10 highly reliable off-nuclear (> 2 kpc) X-ray sources at z=0.03-0.25 in late-type host galaxies within the two GOODS fields (i.e., the two Chandra D…
