Cosmology-Large Scale Structure-Galaxies
Scientific paper
Fractal dimensions in the large scale distribution of galaxies have been calculated with the method given by Wen et al.[1] Samples are taken from CfA redshift survey in northern and southern galactic[2] hemisphere in our analysis respectively. Results from these two regions are compared with each other. There are significant differences between the distributions in these two regions. However, our analyses do show some common features of the distributions in these two regions. All subsamples show multi-level fractal character distinctly. Combining it with the results from analyses of samples given by IRAS galaxies and results from samples given by redshift survey in pencil-beam fields,[3,4] we suggest that multi-level fractal structure is most likely to be a general and important character in the large scale distribution of galaxies. The possible implications of this character are discussed.
