OBSERVATIONS OF TWO HIGH IONIZATION SEYFERT GALAXIES
ABSTRACT
We propose the observations of two ``high ionization'' Seyfert galaxies. They shows high ionization optical lines such as [Fe X], [Fe XI], [Fe IX]. If these ions are generated by photoionization, their ionization state corresponds to that of the warm absorber. However, these galaxies are weak in the soft X-ray band. Therefore, it is uncertain whether or not these iron ions are generated by photoionization. However, there are several signs which imply the presence of the hidden nucleus in each galaxy. ASCA observations will certainly clarify whether or not the presence of the hidden nuclei. If they are present, these observations will give us the clues to link these iron lines and the warm absorber and to clarify the location and physical state of the warm absorber.
