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…
Long-lived transient structure in collisionless self-gravitating systems
David Benhaiem, Francesco Sylos Labini, Michael Joyce
The evolution of self-gravitating systems, and long-range interacting systems more generally, from initial configurations far from dynamical equilibrium is often described as a sim…
Nonaxisymmetric models of galaxy velocity maps
Francesco Sylos Labini, David Benhaiem, Sebastien Comeron +1
Galaxy velocity maps often show the typical pattern of a rotating disk, consistent with the dynamical model where emitters rotate in circular orbits around the galactic center. The…
Transient spiral arms from far out of equilibrium gravitational evolution
David Benhaiem, Michael Joyce, Francesco Sylos Labini
We describe how a simple class of out of equilibrium, rotating and asymmetrical mass distributions evolve under their self-gravity to produce a quasi-planar spiral structure surrou…
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…
Formation of satellites from cold collapse
David Benhaiem, Francesco Sylos Labini
We study the collapse of an isolated, initially cold, irregular (but almost spherical) and (slightly) inhomogeneous cloud of self-gravitating particles. The cloud is driven towards…
