Description:
A sample of about 150 AGNs was selected from observations of Chandra
and XMM X-ray observatories in a 300arcmin2 region of the extended
Groth strip (EGS), and observed by the IRAC and MIPS instruments of
the Spitzer IR telescope. About 68-80% of these sources were detected
by Spitzer, and they show a wide range of mid-infrared properties.
The IRAC SED type does not directly correspond to X-ray spectral type
(hard/soft). The mid-IR properties of X-ray-detected Lyman break,
radio, submillimeter, and optically faint sources vary widely, and for
the most part are not distinct from those of the general X-ray/IR
source population. X-ray sources emit 6-11% of the integrated mid-IR
light, making them significant contributors to the cosmic infrared
background.
