Accretion Disk Structure and Kinematics of the Broad Line Regions in Selected AGN

Accretion Disk Structure and Kinematics of the Broad Line Regions in Selected AGN

Broad emission line regions in AGN are connected with the outer layers of accretion disks. This has been shown by means of line variability studies of individual AGN as well as line profile studies of AGN samples. We could model the broad-line profiles in AGN in a simple way only through rotational...
