Testing growth rate dependence in cosmological perturbation theory using scale-free models
Azrul Pohan, Michael Joyce, David Benhaiem +1
We generalize previously derived analytic results for the one-loop power spectrum (PS) in scale-free models (with linear PS ) to a broader class of such models in…
Particle number dependence in the non-linear evolution of N-body self-gravitating systems
David Benhaiem, Michael Joyce, Francesco Sylos Labini +1
Simulations of purely self-gravitating N-body systems are often used in astrophysics and cosmology to study the collisionless limit of such systems. Their results for macroscopic q…
Stable clustering and the resolution of dissipationless cosmological N-body simulations
David Benhaiem, Michael Joyce, Francesco Sylos Labini
The determination of the resolution of cosmological N-body simulations, i.e., the range of scales in which quantities measured in them represent accurately the continuum limit, is…
Self-similarity and stable clustering in a family of scale-free cosmologies
David Benhaiem, Michael Joyce, Bruno Marcos
We study non-linear gravitational clustering from cold gaussian power-law initial conditions in a family of scale-free EdS models, characterized by a free parameter fixing the…
Exponents of non-linear clustering in scale-free one dimensional cosmological simulations
David Benhaiem, Michael Joyce, François Sicard
One dimensional versions of cosmological N-body simulations have been shown to share many qualitative behaviours of the three dimensional problem. They can resolve a large range of…
