Scientific paper

The m(z) and theta(z) tests are used to study the determination of the curvature of the space-time and evolutionary characteristics of galaxies and quasars. Data on the luminosity of 169 galaxies and 3683 quasars were obtained in the redshift interval of 0.05-3.8. Data on the angular dimensions of 215 radio galaxies and 296 quasars were obtained in the redshift interval of 0.01-2. It is found that galaxies and quasars form a continuous smooth m(z) curve which strongly deviates from the 5 lg z straight line at z greater than 1.
