Redshift Evolution and Non-Universal Dispersion of Quasar Luminosity Correlation

Zhuoyang Li, Lu Huang, Junchao Wang

The standard $\Lambda$CDM model is recently reported to deviate from the high-redshift Hubble diagram of type Ia supernovae (SNe) and quasars (QSOs) at $\sim 4\sigma$ confidence level. In this…
