Abstract

The southern CfA2 galaxy data are used to investigate the scaling properties of the galaxy number distribution. We construct two volume-limited samples with galaxy magnitudes [FORMULA] and [FORMULA], and calculate the second- to ninth-order moments with the box-counting method. On scales from 5 to 27 [FORMULA] M pc, the moments exhibit multifractal scalings. From the exponents of the scalings, we suggest that the galaxies lie in planar structures which have filamentary dense regions.

Key words: methods: statistical – cosmology: large-scale structure of Universe
