Relaxation of One-dimensional Collisionless Gravitating Systems
Eric I. Barnes, Robert J. Ragan
In an effort to better understand collisionless relaxation processes in gravitational systems, we investigate one-dimensional models. Taking advantage of a Hermite-Legendre expansi…
Predicting Steady States of One-dimensional Collisionless Gravitating Systems
Robert J. Ragan, Eric I. Barnes
Building on the development of a Hermite-Legendre analysis of one-dimensional gravitating collisionless systems, we present a technique for determining the steady states of such sy…
Triaxiality Inhibitors in N-Body Simulations
Eric I. Barnes, Evan Dowling
Numerous previous studies have investigated the phenomenon wherein initially spherical N-body systems are distorted to triaxial shapes. We report on an investigation of a previousl…
Comparing Extended System Interactions with Motions in Softened Potentials
Eric I. Barnes
Using an -body evolution code that does not rely on softened potentials, I have created a suite of unbound interacting cluster pair simulations. The motions of the centers of ma…
Entropy Production in Collisionless Systems. III. Results from Simulations
Eric I. Barnes, Colin P. Egerer
The equilibria formed by the self-gravitating, collisionless collapse of simple initial conditions have been investigated for decades. We present the results of our attempts to des…
Dynamics of One-dimensional Self-gravitating Systems Using Hermite-Legendre Polynomials
Eric I. Barnes, Robert J. Ragan
The current paradigm for understanding galaxy formation in the universe depends on the existence of self-gravitating collisionless dark matter. Modeling such dark matter systems ha…
