1E 0117.2-2837 and the NLR of Narrow-Line Seyfert 1 galaxies
S. Komossa, D. Grupe, M. Janek
Abstract
Based on photoionization calculations we present a study of the NLR emission line ratios of Narrow-line Seyfert 1 (NLS1) galaxies. In particular, we investigate the influence of different EUV - soft-X-ray spectral shapes (a giant soft excess, a steep X-ray powerlaw, the presence of a warm absorber) and NLR cloud properties (density, abundances, distance from the continuum source) on the predicted optical emission-line ratios like [OIII] and [FeXIV].
