Abstract:
We investigate the nature of a sample of 92 Spitzer MIPS 24µm-
selected galaxies in the CDF-S, showing power-law-like emission in the
Spitzer IRAC 3.6-8µm bands. The main goal is to determine whether
the galaxies not detected in X-rays (47% of the sample) are part of
the hypothetical population of obscured AGNs not detected even in deep
X-ray surveys.
Description:
We have obtained 24 and 70µm MIPS observations of the CDF-S
covering a total area of 1.5°*0.5°. In this work we focus only
on the field of view (FOV) with Chandra coverage
