Scales of Structures and Homogeneity in the Universe

A low-resolution objective prism redshift survey of southern galaxies (15 <m <20, z <=0.3) provides 46,000 redshifts with errors 0.010 <= σ_z_<= 0.013 from which subsamples are drawn for studies of large-scale structures and scales of homogeneity in the universe. The derived mean number density for galaxies with -20.8<=M<=-19.2 is 0.024h^3^Mpc^-3^ in a total volume of 1.5 x 10^6^h^-3^Mpc^3^. Maximum density deviations, tested with galaxies -20.8<=M<=-20.2 lie between 10% and 30% in comoving test volumes of 5 x 10^4^h^-3^ Mpc^3^, shifted over 10^5^h^-3^ Mpc^3^. The present data appear to be incompatible with the presence of 100h^-1^ Mpc voids.
