Quasi-local evolution of cosmic gravitational clustering in weakly non-linear regime
We investigate the weakly non-linear evolution of cosmic gravitational clustering in phase space by looking at the Zel’dovich solution in the discrete wavelet transform (DWT) representation. We show that if the initial perturbations are Gaussian, the relation between the evolved DWT mode and the initial perturbations in the weakly non-linear regime is quasi-local. That is, the evolved density p...
متن کاملQuasilocal gravitational energy.
Abstract. A dynamically preferred quasi-local definition of gravitational energy is given in terms of the Hamiltonian of a ‘2+2’ formulation of general relativity. The energy is well-defined for any compact orientable spatial 2-surface, and depends on the fundamental forms only. The energy is zero for any surface in flat spacetime, and reduces to the Hawking mass in the absence of shear and twi...
متن کاملQuasi-Local Evolution of the Cosmic Gravitational Clustering in Halo Model
We show that the nonlinear evolution of the cosmic gravitational clustering is approximately spatial local in the x-k (position-scale) phase space if the initial perturbations are Gaussian. That is, if viewing the mass field with modes in the phase space, the nonlinear evolution will cause strong coupling among modes with different scale k, but at the same spatial area x, while the modes at dif...
متن کاملNonlinear Gravitational Clustering in Expanding Universe
The gravitational clustering of collisionless particles in an expanding universe is modelled using some simple physical ideas. I show that it is possible to understand the nonlinear clustering in terms of three well defined regimes: (1) linear regime; (2) quasilinear regime which is dominated by scale-invariant radial infall and (3) nonlinear regime dominated by nonradial motions and mergers. M...
متن کاملWeakly Nonlinear Clustering for Arbitrary Expansion Histories
Bouchet et al. (1992) showed that in an open or closed Universe with only pressureless matter, gravitational instability from Gaussian initial conditions induces a normalized skewness, S3 ≡ 〈δ 〉 〈δ〉 −2 , that has only a very weak dependence on the nonrelativistic-matter density. Here we generalize this result to a plethora of models with various contributions to the total energy density, includ...
