Query: On how much X-ray and UV radiation processes are coupled in accretion
  disks: AGN case   Within the standard accretion disk theory for active galactic nuclei (AGN),
the observed X-rays are often modeled by Compton up-scattering of ultraviolet
(UV) disk photons inside a hot disk corona. Here, we point out that for many
AGN, radiation pressure due to the very same UV disk photons can drive a flow
from the disk into the corona and couple the processes producing X-rays and UV
photons. This coupling could lead to quenching of the disk corona because the
regions above the UV disk will be too dense, too opaque, and consequently too
cold. We discuss various consequences of this new type of the X-ray/UV coupling
on the dynamical and radiative properties of AGN.
