Issue Date: | 2018 | Journal: | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY | Number: | 479 | Issue: | 4 | First Page: | 5022 | 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; N<SUB>H</SUB> below and above 10<SUP>21.5</SUP> cm<SUP>-2</SUP>), including their X-ray luminosity L<SUB>X</SUB>, black hole mass, Eddington ratio λ<SUB>Edd</SUB>, optical continuum, and line features. We find that BLAGN2 have systematically larger broad line widths and hence apparently higher (lower) M<SUB>BH</SUB> (λ<SUB>Edd</SUB>) 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. <P /> | URI: | http://hdl.handle.net/20.500.12386/28406 | URL: | https://academic.oup.com/mnras/article-abstract/479/4/5022/5049307 | ISSN: | 0035-8711 | DOI: | 10.1093/mnras/sty1751 | Bibcode ADS: | 2018MNRAS.479.5022L | Fulltext: | open |
