Scientific paper

The paper examines the evolution of quasars with resolved components and determines their deceleration parameter. The redshift-magnitude relation and the deceleration parameter are derived using the maximum separation D of the components as a parameter for the standard candle classification of composite quasars. This shows that the universe is probably closed, and the statistics indicate that only quasars with smaller D existed during the early stages of the universe, and quasars with larger D appeared only in the later stages. This supports the 'big bang' universe model; statistical results also show that the optical and radio luminosities of these quasars gradually decrease during their evolution.
