Coronal lines and the warm X-ray absorber in Seyfert 1 Galaxies
Abstract
The connection between the coronal lines and the warm absorber is examined systematically. In an earlier work it was found that the coronal line emitting plasma and the warm absorber gas share the same density and temperature. If there is a connection between the warm absorber gas and the forbidden high-ionization line (FHIL) plasma, one can use the profiles of coronal lines to derive the kinematics and dynamics of the warm absorber due to the high spectral resolution available in the optical range. Further support for a connection is a correlation between the equivalent width of [Fe X] 6375 and the ROSAT spectral index found for an optically selected sample. For X-ray selected objects with absorption edges observed by ASCA, we looked for a correlation between the coronal lines and the warm absorber gas. A direct correlation cannot be confirmed.
