Observing the Unobservable: Coronal Line Data from NLS1s as a Test of EUV Continuum Models
P. J. Bleackley, P. T. O'Brien
Abstract
We have measured coronal line emission for a sample of 19 Narrow-Line Seyfert~1 galaxies. Kinematic analysis shows that the Coronal Line Region (CLR) consists of gas in a decelerating outflow. We intend to use these data as a test of the EUV emission of NLS1s. By comparison with photoionization modelling for a number of power-law + black body spectra, we plan to deduce the most likely EUV continua for these objects as well as explore physical conditions in the CLR.
