An Indicator of Nonlinear Gravitational Clustering
J. S. Bagla
Alignment of velocity and acceleration before shell crossing, and later misalignment are used to define velocity contrast, an indicator of dynamical state of matter undergoing grav…

Evolution Of Gravitational Potential In The Quasilinear And Nonlinear Regimes
J. S. Bagla, T. Padmanabhan
We study the evolution of the power spectrum of gravitational potential during the nonlinear clustering in an matter dominated phase. N-body simulations suggest that the pote…
