The relation between the two-point and the three-point correlation functions in the non-linear gravitational clustering regime
Hiroko Koyama, Taihei Yano
The connection between the two-point and the three-point correlation functions in the non-linear gravitational clustering regime is studied. Under a scaling hypothesis, we find tha…
Universality in the distribution of caustics in the expanding Universe
Taihei Yano, Hiroko Koyama, Thomas Buchert +1
We numerically investigate the long--time evolution of density perturbations after the first appearance of caustics in an expanding cosmological model with one--dimensional `single…
Long-time behavior and relaxation of power-law correlation in one-dimensional self-gravitating system
Hiroko Koyama, Tetsuro Konishi
Long-time behavior of spatial power-law correlation in one-dimensional self-gravitating system is numerically investigated. It is found that the power-law structure persists even a…
Hierarchical clustering and formation of power-law correlation in 1-dimensional self-gravitating system
Hiroko Koyama, Tetsuro Konishi
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 gro…
