%0 Journal Article %T Hierarchical clustering and formation of power-law correlation in 1-dimensional self-gravitating system %A Hiroko Koyama %A Tetsuro Konishi %J Physics %D 2000 %I arXiv %R 10.1209/epl/i2002-00646-4 %X The process of formation of fractal structure in one-dimensional self-gravitating system is examined numerically. It is clarified that structures created in small spatial scale grow up to larger scale through clustering of clusters, and form power-law correlation. %U http://arxiv.org/abs/astro-ph/0008507v1
