We recently studied the energy behavior of a quantum-corrected time-dependent
black hole. The system analyzed was a quantum-corrected Kerr solution that
settles down to a stationary configuration as the time dependence fades out. A
trans-Planckian energy scaling in the vicinity of the event horizon resulted,
and we proposed the trans-Planckian radiation to be the missing link in the
glowing mechanism of active galactic nuclei. The main goal of the present work
is to examine the scaling and structure of the radiation by analyzing the
quantum momentum density. We again observe a trans-Planckian behavior.
Furthermore, the momentum density displays structures that are indicative of a
disk-like configuration near the equator and a collimated outflow of matter
from the poles. The bipolar outflow (disk-like structure) should be an
essential part of the underlying mechanism for jets (accretion disks) of active
galactic nuclei.
