Connection between spectral complexity and X-ray weakness: testing the reflection interpretation
Abstract
In recent work it was demonstrated that narrow-line Seyfert 1 galaxies, which possessed spectral complexity in the 2-10 keV band were at the same time X-ray weak. In this contribution I show how X-ray weakness can be understood in the context of reflection and light bending picture. In fact, X-ray weakness should be expected from objects that are in a reflection dominated state. With simultaneous UV and X-ray data available with most XMM-Newton observations, an estimate of the X-ray weakness is relatively straightforward. As such, it is an easy way to substantiate conclusions of reflection dominated spectra, and we use this method to examine recent claims.
