Description
Instead of a toroidal hydrostatic structure, disk outflow too can explain AGN obscuration. A central component of star formation, such outflows unify naturally many AGN observations, including broad line emission. Disk winds predict that both the torus and BLR disappear at low black-hole accretion rates, as observed. Recent observations reveal two stages in the broad line disappearance. In this talk I will offer an explanation that incorporates as a byproduct the "intermediate" Seyfert galaxies (type 1.x) into the unification scheme.
