EUV continuum of narrow-line Seyfert 1 galaxies
Abstract
We study the NLR emission line spectrum of 12 NLS1s to constrain the EUV - soft X-ray continuum SED using accurate photoionization modeling. We find that the NLR emission line ratios, which we measure for several NLS1 galaxies, can be reproduced within ±15% without a strong BBB component in the framework of a two-component model.
