ADC_Keywords: Active gal. nuclei ; Infrared sources ; X-ray sources Keywords: galaxies: active - galaxies: high-redshift - infrared: galaxies - X-rays: galaxies 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 File Summary:
