An X-ray Baldwin effect for the narrow Fe K-alpha lines observed in Active Galactic Nuclei
K. L. Page, P. T. O'Brien, J. N. Reeves +1
The majority of Active Galactic Nuclei (AGN) observed by XMM-Newton reveal narrow Fe K-alpha lines at ~ 6.4 keV, due to emission from cold (neutral) material. There is an X-ray Bal…
