Description
Here we present the 12-year spectral optical monitoring campaign of the NLSy1 galaxy
Ark 564. The research was focused on the analysis of line and continuum light curves
with the aim to study the physics of the broad line region. Special attention was given
to the analysis of the ionized iron emission, since in this object these lines are strong
and can be distinguished from other near-by emission lines. Some interesting results are
outlined, such as the lack of correlation between the broad Balmer lines, or different
degrees of correlation between the continuum flux and Fe II emission from different spectral
multiplets.
