Scientific paper

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 M_{B(0)} <= -19.42 and M_{B(0)} <= -20.00, and calculate the second- to ninth-order moments with the box-counting method. On scales from 5 to 27 h(-1) Mpc, 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.
