Abstract / Description:This paper describes the selection of a new southern/equatorial sample of gigahertz peaked spectrum (GPS) radio galaxies, and subsequent optical charge-coupled device imaging and spectroscopic observations using the ESO 3.6-m telescope. The sample consists of 49 sources with -40degrees < δ < + 15degrees, \b\>20degrees and S-2.7GHz > 0.5 Jy, selected from the Parkes PKSCAT90 survey. Approximately 80 per cent of the sources are optically identified, and approximately half of the identifications have available redshifts. The R-band Hubble diagram and evolution of the host galaxies of GPS sources are reviewed.
