Influence of Comptonization region over the ambiance of accretion disc
  in Active Galactic Nucleus
  Understanding the radiative and physical structures of inner region of a few
100 pc of AGNs is important to constrain the causes of their activities.
Although the X-ray emission from the Comptonization region/corona and the
accretion disc regulates the broad line emission regions and torus structures,
the exact mutual dependency is not understood well. We performed correlation
studies for X-ray, mid-infrared, and different components of Balmer emission
lines for the selected sample of AGNs. Almost 10 different parameters and their
inter-dependencies were explored in order to understand the underlying
astrophysics. We found that the X-ray luminosity has a linear dependency on the
various components of broad Balmer emission lines (e.g. L$_{\text{2-10 keV}}$
$\propto$ L$^{0.78}_{\text{H}\beta^{\text{B}}}$) and found a strong dependency
on the optical continuum luminosity (L$_{\text{2-10 keV}}$ $\propto$
L$^{0.86}_{5100\,\text{\AA}}$). For a selected sample, we also observed a
linear dependency between X-ray and mid-infrared luminosity (L$_{\text{2-10
keV}}$ $\propto$ L$^{0.74}_{6\,\upmu \text{m}}$). A break point was observed in
our correlation studies for X-ray power-law index, $\Gamma$, and mass of black
hole at $\sim$ log (M/M$_{\odot}$) = 8.95. Similarly the relations between
$\Gamma$ and FWHM of H$\alpha$ and H$\beta$ broad components show breaks at
FWHM$_{\text{H}\alpha}$= 7642$\pm$657 km s$^{-1}$ and FWHM$_{\text{H}\beta}$ =
7336$\pm$650 km s$^{-1}$. However, more data are required to confine the breaks
locations exactly. We noted that $\Gamma$ and Eddington ratios are negatively
correlated to Balmer decrements in our selected sample. We analyzed and
discussed about the implications of new findings in terms of interaction AGN
structures.
