Abstract:
We present mid-infrared observations of active galactic nuclei (AGNs)
in the GOODS fields, performed with the Spitzer Space Telescope. These
are the deepest infrared and X-ray fields to date and cover a total
area of 0.1°2. AGNs are selected on the basis of their hard
(28keV) X-ray emission.
Description:
The GOODS-North and South fields, which cover ∼160arcmin2 each, were
observed with the Spitzer Space Telescope as part of the GOODS Legacy
program (PI: M. Dickinson). Observations were performed using the IRAC
camera in the four available bands (3.6-8µm) and the MIPS
instrument in the 24µm band.

Note (1): Probability of random association assuming a Poissonian
distribution of sources. Expression 1-exp(-nπd2) was used
where n is the density of sources and d is the distance between
the X-ray and infrared sources.
Note (2): In units of erg/cm2/s.
Note (3): Defined as (H-S)/(H+S) where H and S are the background-substracted
counts in the Hard and Soft X-ray bands respectively.
Note (4): Redshift type, defined as follows:
S = Spectroscopic Redshift;
P = Photometric Redshift;
N = No redshift measured.
Note (5): Optical classification, defined as follows:
B = Broad line AGN;
N = Narrow line AGN;
G = Galaxy;
U = Unknown.
