Implications of infalling Fe II - emitting clouds in active galactic nuclei: anisotropic properties
Gary J. Ferland, Chen Hu, Jian-Min Wang +4
We investigate consequences of the discovery that Fe II emission in quasars, one of the spectroscopic signatures of "Eigenvector 1", may originate in infalling clouds. Eigenvector…
