Abstract
Using the X-ray-selected active galactic nuclei (AGN) from the XMM-XXL north survey and the Sloan Digital Sky Survey-Baryon Oscillation Spectroscopic Survey spectroscopic follow-up of them, we compare the properties of X-ray unobscured and obscured broad-line AGN (BLAGN1 and BLAGN2; NH below and above 1021.5 cm-2), including their X-ray luminosity LX, black hole mass, Eddington ratio λEdd, optical continuum, and line features. We find that BLAGN2 have systematically larger broad line widths and hence apparently higher (lower) MBH (λEdd) than BLAGN1. We also find that the X-ray obscuration in BLAGN tends to coincide with optical dust extinction, which is optically thinner than that in narrow-line AGN (NLAGN) and likely partial covering to the broad-line region. All the results can be explained in the framework of a multicomponent, clumpy torus model by interpreting BLAGN2 as an intermediate type between BLAGN1 and NLAGN in terms of an intermediate inclination angle.
