Gravitational collapse from cold uniform asymmetric initial conditions

  title={Gravitational collapse from cold uniform asymmetric initial conditions},
  author={Francesco Sylos Labini and Michael Joyce},
  journal={Astronomy \& Astrophysics},
Using controlled numerical N-body experiments, we show how, in the collapse dynamics of an initially cold and uniform distribution of particles with a generic asymmetric shape, finite N fluctuations and perturbations induced by the anisotropic gravitational field compete to determine the physical properties of the asymptotic quasi-stationary state. When finite N fluctuations dominate the dynamics, the particle energy distribution changes greatly and the final density profile decays outside its…

Angular momentum generation in cold gravitational collapse

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 this mass can

Energy ejection in the collapse of a cold spherical self-gravitating cloud

When an open system of classical point particles interacting by Newtonian gravity collapses and relaxes violently, an arbitrary amount of energy may, in principle, be carried away by particles which

Universal properties of violently relaxed gravitational structures

We study the collapse and virialization of an isolated spherical cloud of self-gravitating particles initially at rest and characterised by a power-law density profile, with exponent 0<= \alpha < 3,

Spherical symmetry breaking in cold gravitational collapse of isolated systems

We study, using $N$-body simulation, the shape evolution in gravitational collapse of cold uniform spherical system. The central interest is on how the deviation from spherical symmetry depends on

Scaling up tides in numerical models of galaxy and halo formation

ABSTRA C T The purpose of this article is to show that when dynamically cold, dissipationless selfgravitating systems collapse, their evolution is a strong function of the symmetry in the initial

Constrained Violent Relaxation to a Spherical Halo

Violent relaxation during the collapse of a galaxy halo is known to be incomplete in realistic cases such as cosmological infall or mergers. We adopt a physical picture of strong but short-lived

On the generation of triaxiality in the collapse of cold spherical self-gravitating systems

Initially cold and spherically symmetric self-gravitating systems may give rise to a virial equilibrium state which is far from spherically symmetric, and typically triaxial. We focus here on how the

Violent relaxation of ellipsoidal clouds

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 in the mechanism

Formation of satellites from cold collapse

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 a virialized

Limitation of symmetry breaking by gravitational collapse: the revisit of Lin–Mestel–Shu instability

We revisit the topic of shape evolution during the spherical collapse of an $N$-body system. Our main objective is to investigate the critical particle number below which, during a gravitational
