BAT AGN Spectroscopic Survey -IV. : near-infrared coronal lines, hidden broad lines and correlation with hard X-ray emission
(2017) [Artigo de periódico]We provide a comprehensive census of the near-infrared (NIR, 0.8–2.4 μm) spectroscopic properties of 102 nearby (z < 0.075) active galactic nuclei (AGN), selected in the hard X-ray band (14–195 keV) from the Swift-Burst ... -
The evolution of active galactic nuclei in clusters of galaxies from the Dark Energy Survey
(2017) [Artigo de periódico]The correlation between active galactic nuclei (AGNs) and environment provides important clues to AGN fuelling and the relationship of black hole growth to galaxy evolution. In this paper, we analyse the fraction of galaxies ...
