    The hard X-ray perspective on the soft X-ray excess 
    Vasudevan, Ranjan V.; Mushotzky, Richard F.; Reynolds, Christopher S.; Fabian, Andrew C.; Lohfink, Anne M.; Zoghbi, Abderahmen; Gallo, Luigi C.; Walton, Dominic (IOP Publishing Limited, 2014-04-10)
    The X-ray spectra of many active galactic nuclei exhibit a “soft excess” below 1 keV, whose physical origin remains unclear. Diverse models have been suggested to account for it, including ionized reflection ...

    High Density Reflection Spectroscopy – II. the density of the inner black hole accretion disc in AGN 
    Jiang, Jiachen; Fabian, Andrew C.; Dauser, Thomas; Gallo, Luigi C.; Garcia, Javier A.; Kara, Erin; Parker, Michael L.; Tomsick, John A.; Walton, Dominic J.; Reynolds, Christopher S. (Oxford University PressRoyal Astronomical Society, 2019-08-22)
    We present a high density disc reflection spectral analysis of a sample of 17 Seyfert 1 galaxies to study the inner disc densities at different black hole mass scales and accretion rates. All the available XMM– ...
