The Origin of the soft excess in AGN
Chris Done, Marek Gierlinski, Malgosia Sobolewska +1
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 ionised rath…
Iron Kalpha emission from the low-luminosity Active Galaxies M81 and NGC 4579
G. C. Dewangan, R. E. Griffiths, T. Di Matteo +1
We report on XMM-Newton spectroscopy of the low-luminosity active galaxies (LLAGN) M81 and NGC4579 both of which have known black hole masses and well-sampled spectral energy distr…
Iron Features in the XMM-Newton spectrum of NGC 4151
N. J. Schurch, R. S. Warwick, R. E. Griffiths +1
We present a detailed analysis of the hard X-ray (>2.5 keV) EPIC spectra from the first observations of NGC 4151 made by XMM-Newton. We fit the spectra with a model consisting of a…
