Observations Favor the Redshift-evolutionary L X–L UV Relation of Quasars from Copula
The Astrophysical JournalWe compare, with data from quasars, Hubble parameter measurements, and Pantheon+ type Ia supernova, three different relations between X-ray luminosity ( L _X ) and ultraviolet luminosity ( L _UV ) of quasars. These three relations consist of the standard
