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…

Evolution of gaseous disk viscosity driven by supernova explosion in star-forming galaxies at high redshift
Jian-Min Wang, Chang-Shuo Yan, Yan-Rong Li +5
Motivated by Genzel et al.'s observations of high-redshift star-forming galaxies, containing clumpy and turbulent rings or disks, we build a set of equations describing the dynamic…

Episodic Random Accretion and the Cosmological Evolution of Supermassive Black Hole Spins
J. -M. Wang, C. Hu, Y. -R. Li +7
The growth of supermassive black holes (BHs) located at the centers of their host galaxies comes mainly from accretion of gas, but how to fuel them remains an outstanding unsolved…
