Fraction of the X-ray selected AGNs with optical emission lines in galaxy groups
Feng Li, Qirong Yuan, Weihao Bian +2
Compared with numerous X-ray dominant active galactic nuclei (AGNs) without emission-line signatures in their optical spectra, the X-ray selected AGNs with optical emission lines a…
Variation of ionizing continuum: the main driver of Broad Absorption Line Variability
Zhicheng He, Tinggui Wang, Hongyan Zhou +5
We present a statistical analysis of the variability of broad absorption lines (BALs) in quasars using the large multi-epoch spectroscopic dataset of the Sloan Digital Sky Survey D…
Unveiling slim accretion disc in AGN through X-ray and Infrared observations
Núria Castelló-Mor, Shai Kaspi, Hagai Netzer +7
In this work, which is a continuation of Castelló-Mor et al. (2016), we present new X-ray and infrared (IR) data for a sample of active galactic nuclei (AGN) covering a wide range…
