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 active galactic nucleus (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 interdependencies 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. L2-10 (keV) proportional to L-H beta B(0.78)) and found a strong dependency on the optical continuum luminosity (L2-10 (keV) proportional to L-5100 angstrom(0.86)) For a selected sample, we also observed a linear dependency between X-ray and mid-infrared luminosity (L2-10 (keV) proportional to L6(mu m)(0.74)) A break point was observed in our correlation studies for X-ray power-law index, Gamma, and mass of black hole at similar to log (M/M-circle dot) = 8.95. Similarly, the relations between Gamma and full width at half-maximum (FWHM) of H alpha and H beta broad components show breaks at FWHMH alpha = 7642 +/- 657 km s(-1) and FWHMH beta = 7336 +/- 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 analysed and discussed about the implications of new findings in terms of interaction AGN structures.
