Numerical Investigation of Non-Homologous Collapse of the One-Dimensional Gravitational Gas

Numerical Investigation of Non-Homologous Collapse of the One-Dimensional Gravitational Gas

In this paper, the one-dimensional gravitational gas is evolved numerically using an eventdriven code. Two initial conditions are considered: (1) an initially uniform isolated system withno velocity dispersion and where the initial velocities are sine functions of the position, and (2)two “clusters”...
