Angular Correlations of Galaxy Distribution

We study the angular correlations of various galaxy catalogs (the CfA1, SSRS1, Perseus-Pisces, APM Bright Galaxies, and Zwicky catalogs). We find that the angular correlation exponent is gamma a = 0.1 +/- 0.1 rather than gamma a = 0.7, as usually found by the standard correlation function omega ( theta ). We identify the problem in the artificial decay of omega ( theta ). Moreover, we find that no characteristic angular scale is present in any of the analyzed catalogs. Finally, we show that all the available data are consistent with each other, and the angular distribution of galaxies is quite naturally compatible with a fractal structure with D ~ 2.
