The redshift and X-ray photon index evolutionary LX-LUV relations of quasars

The LX-LUV relation serves as a cornerstone for extending the Hubble diagram to higher redshift by utilizing quasars as standard candles. However, the constancy of the LX-LUV relation has been embroiled in controversy recently. In this work, we discuss the possible physical origins of evolution in t...
