Scientific paper

One of the most important issue in observational cosmology is the identification of the homogneity scale, i.e. the scale beyond which a constant density can be defined. In this respect, the authors study the Perseus Pisces redshift survey. They find that this sample shows no tendency towards homogenization, and that the galaxy distribution has a fractal long-range correlation up to the sample depth (≍130 h-1 Mpc), with fractal dimension D ≍ 2. Moreover, the authors find clear evidence that the luminosity segregation phenomenon has no observational base.
