Infrared Number Counts of AGN in the GOODS Fields
E. Treister, C. Megan Urry, the GOODS AGN Team
Using the known numbers and evolution of unobscured AGN, and assuming that there is a large number of corresponding obscured AGN -- as expected if AGN unification is correct -- we…
Infrared Properties of AGN in the GOODS Fields: AGN in Stellar Dominated High-z Galaxies
Jeffrey Van Duyne, C. Meg Urry, Eleni Chatzichristou +2
We present analysis of spectral energy distributions (SEDs) from mid-infrared through X-ray of a sample of 420 hard X-ray selected, z-band and Spitzer/IRAC detected active galactic…
Multicolour Optical Imaging of IR-Warm Seyfert Galaxies. IV. Surface Photometry: Colour Distributions
Eleni T. Chatzichristou
This paper is the fourth in a series, studying the optical properties of a sample of mid-IR Warm Seyfert galaxies and of a control sample of mid-IR cold galaxies. The present paper…
