| Abstract: |
Photoionization modeling codes have been developed over the last three decades,
achieving powerful predictions based on a high degree of complexity in terms of
the physical processes considered in the simulations. Nevertheless, the temporal
dependency of the equations is usually neglected or included through very simplistic
approximations. Here we present the efforts on the development of a self-consistent
photoionization model where the energy, ionization balance and radiative transfer
equations are considered in their full time-dependent form. With these models we
are able to predict the departures from the steady-state of a photoionized gas
given the time variability of the radiation source. These results are particularly
applicable to active galactic nuclei outflows where the energy source, the
optical/UV/X-ray continuum, is highly variable. |
