| Abstract: |
We discuss various ideas for the origin of the soft X-ray excess seen in AGN. There are clear advantages to models where this arises from atomic processes in partially ionized rather than where it is a true continuum component. However, current data cannot distinguish between models where this material is seen in reflection or absorption. While higher energy data may break the degeneracies, we also suggest that strong outflows are extremely likely to be present, lending more physical plausibility to an absorption origin. This more messy picture of NLS1s means that they are probably not good places to test General Relativity, but they do give insight into the spectra expected from the first QSOs in the early Universe. |
