We propose a modified version of the observed non-linear relation between the X-ray (2 keV) and the ultraviolet (2,500 Å) emission in quasars (i.e., LX ∝ LγUV) which involves the full width at half-maximum, FWHM, of the broad emission line, i.e., LX ∝ Lγ̂UV FWHM β̂ . By analyzing a sample of 550 optically selected non-jetted quasars in the redshift range of 0.36–2.23 from the Sloan Digital Sky Survey cross matched with the XMM-Newton catalog 3XMM-DR6, we found that the additional dependence of… CONTINUE READING
