VizieR Online Data Catalog: X-ray properties of 26 high-luminosity quasars (Timlin+, 2021)
Abstract
In this work, we presented the first, large-scale investigation of the joint relationships between αox, HeII EW, and L2500. We gathered 206 quasars that have high-quality spectral coverage of the rest-frame UV and have sensitive X-ray coverage with Chandra or XMM-Newton; these span wide ranges of both luminosity and redshift.
