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…
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…
Angular momentum generation in cold gravitational collapse
D. Benhaiem, M. Joyce, F. Sylos Labini +1
During the violent relaxation of a self-gravitating system a significant fraction of its mass may be ejected. If the time varying gravitational field also breaks spherical symmetry…
Violent relaxation of ellipsoidal clouds
David Benhaiem, Francesco Sylos Labini
An isolated, initially cold and ellipsoidal cloud of self-gravitating particles represents a relatively simple system to study the effects of the deviations from spherical symmetry…
