Scientific paper

The magnitude-redshift relation, the color-redshift relation, the galaxy number count, the redshift distribution of galaxies, and the extragalactic background light are calculated taking into account the effect of galactic evolution for several values of the cosmological deceleration parameter q0 and the redshift of galaxy formation zF. The spectral evolutions of galaxies for five morphological types E/S0, Sab, Sbc, Scd, and Sdm are simulated. It is found that all the existing data are compatible with the deceleration parameter q0 ≡ 0.5 provided that galaxies are formed at redshift zF ≡ 3 - 5.
