MID-INFRARED SELECTION OF ACTIVE GALACTIC NUCLEI WITH THE WIDE-FIELD INFRARED SURVEY EXPLORER. I. CHARACTERIZING WISE-SELECTED ACTIVE GALACTIC NUCLEI IN COSMOS
The Wide-field Infrared Survey Explorer (WISE) is an extremely capable and efficient black hole finder. We present a simple mid-infrared color criterion, W1 − W2 ⩾ 0.8 (i.e., [3.4]−[4.6] ⩾0.8, Vega),…
The Infrared Luminosity Function of Galaxies at Redshifts z = 1 and z ~ 2 in the GOODS Fields

We present the rest-frame 8 μm LF at redshifts z = 1 and ~2, computed from Spitzer 24 μm-selected galaxies in the GOODS fields over an area of 291 arcmin2. Using classification criteria based on…

We use very deep Spitzer MIPS 24 μm observations to examine the bolometric luminosities (Lbol) and UV extinction properties of more than 200 spectroscopically identified, optically selected (UnGℛ) z…

The Wide-field Infrared Survey Explorer (WISE) has completed its all-sky survey in four channels at 3.4–22 μm, detecting hundreds of millions of objects. We merge the WISE mid-infrared data with…
A CONTINUUM OF H- TO He-RICH TIDAL DISRUPTION CANDIDATES WITH A PREFERENCE FOR E+A GALAXIES

Spitzer Mid-Infrared Spectroscopy of Infrared Luminous Galaxies at z~2. II. Diagnostics
We present mid-IR spectral decomposition of a sample of 48 Spitzer-selected ULIRGs spanning z ~ 1-3 and likely LIR ~ 1012-1013 L☉. Our study aims at quantifying the star formation and active galactic…
Deep Optical Galaxy Counts with the Keck Telescope
We present faint galaxy counts from deep VRI images obtained with the Keck Telescope. These images reach R ~ 27 in median seeing FWHM ~ 0.″5-0.″6, and we detect a integrated galaxy number density of…
The corals survey I: new estimates of the number density and gas content of damped lyman alpha systems free from dust bias

- 13 September 2001
We present the first results from the Complete Optical and Radio Absorption Line System (CORALS) survey. We have compiled a homogeneous sample of radio-selected QSOs from the Parkes Catalogue and…
