Description
Here we will present some spectroscopic methods for emission gas
research in the emission line region of Active Galactic Nuclei (AGNs):
(1) We will demonstrate the possibility to use the Boltzmann-plot method
to estimate the physical conditions in the broad line regions (BLRs) (2)
We will discuss the applicability of so called ``Gaussian method'' for
spectral line shape investigation of narrow line regions (NLRs) and
BLRs; (3) We will present a method to fit the line profiles with a
kinematically complex model. We apply a two-component model assuming
that the line wings originate in a very broad line region (VBLR) and the
line core in an intermediate line region (ILR) of AGNs. The VBLR is
assumed to be an accretion disk and the ILR a spherical emission region;
(4) Also, a model for fitting of the broad absorption lines in quasars
will be discussed.
