An explanation for the soft X-ray excess in active galactic nuclei
We present a large sample of type 1 active galactic nuclei (AGN) spectra taken with XMM—Newton, and fit them with both the conventional model (a power law and blackbody) and the relativistically blurred photoionized disc reflection model of Ross & Fabian. We find that the disc reflection model is a …
