Abstract

The optical Hubble diagram for a complete sample of 112 quasars is constructed for q ₀ = 1. With no correction for selection effects, the Hubble diagram shows a strong correlation of magnitude with redshift (slope 4.43 ± 0.44; correlation coefficient of 0.956). These uncorrected results place an interesting limit on luminosity evolution. The optical and radio Hubble diagrams are also discussed after applying the proper corrections for selection effects.
