Abstract:
The co-evolution of host galaxies and the active black holes which
reside in their centre is one of the most important topics in modern
observational cosmology. Here we present a study of the properties of
obscured active galactic nuclei (AGN) detected in the CDFS 1 Ms
observation and their host galaxies.
We limited the analysis to the MUSIC area, for which deep K-band
observations obtained with ISAAC@VLT are available, ensuring accurate
identifications of the counterparts of the X-ray sources as well as
reliable determination of photometric redshifts and galaxy parameters,
such as stellar masses and star formation rates. In particular, we: 1)
refined the X-ray/infrared/optical association of 179 sources in the
MUSIC area detected in the Chandra observation; 2) studied the host
galaxies observed and rest frame colors and properties.
