Active Galaxy Nuclei at high redshifts: properties and environment of
  Type 1 and 2 AGNs
  We explore host galaxy properties and environment of a sample of Type 1 and 2
active galactic nuclei (AGN) taken from the COSMOS2015 catalog, within 0.3
$\leq z \leq$ 1.1 selected for their emission in X-rays, optical spectra and
SED signatures. We find different properties of host galaxies of distinct AGNs:
Type 1 AGNs reside in blue, star-forming and less massive host galaxies
compared to Type 2. The majority of the AGNs have intermediate X-ray
luminosities, $10^{42}\leq L_X<10^{44}$ \ergs, while only a few have X-ray
luminosities ($L_X > 10^{44}$ \ergs) as those observed in QSOs. Non-parametric
morphological analysis show that the majority of Type 1 AGN hosts are
elliptical or compact galaxies, while Type 2 AGN host present more scatter,
from spirals, irregulars and elliptical galaxies. The environment of the
different AGN types are similar except at small scales ($r_p<$100 kpc), where
Type 2 AGNs have more neighbour galaxies than Type 1s. Galaxies located close
to Type 2 AGNs ($\sim$100 kpc) tend to have redder colours, and are more
massive compared to the local environment of Type 1s. The observed differences
in the environment and host galaxy properties of Type 1 and 2 AGN types show
that the obscuration due to the presence of gas and dust may be distributed in
larger galactic-scales, possibly originated by galaxy interactions or mergers.
