Multiwavelength morphological study of active galaxies
  Studying the morphology of a large sample of active galaxies at different
wavelengths and comparing it with active galactic nuclei (AGN) properties, such
as black hole mass ($M_{BH}$) and Eddington ratio ($\lambda_{Edd}$), can help
us in understanding better the connection between AGN and their host galaxies
and the role of nuclear activity in galaxy formation and evolution. By using
the BAT-SWIFT hard X-ray public data and by extracting those parameters
measured for AGN and by using other public catalogues for parameters such as
stellar mass ($M_*$), star formation rate (SFR), bolometric luminosity
($L_{bol}$), etc., we studied the multiwavelength morphological properties of
host galaxies of ultra-hard X-ray detected AGN and their correlation with other
AGN properties. We found that ultra hard X-ray detected AGN can be hosted by
all morphological types, but in larger fractions (42%) they seem to be hosted
by spirals in optical, to be quiet in radio, and to have compact morphologies
in X-rays. When comparing morphologies with other galaxy properties, we found
that ultra hard X-ray detected AGN follow previously obtained relations. On the
SFR vs. stellar mass diagram, we found that although the majority of sources
are located below the main sequence (MS) of star formation (SF), still
non-negligible number of sources, with diverse morphologies, is located on
and/or above the MS, suggesting that AGN feedback might have more complex
influence on the SF in galaxies than simply quenching it, as it was suggested
in some of previous studies.
