Treecode2: The Power of Pluralism. I. Static Tests
Joshua E. Barnes
I describe an `oct-tree' N-body code which randomly shifts, reorients, and resizes the root cell at each time step. Averaging over a plurality of root cell positions and orientatio…
Effects of Halo Anisotropy on Disc Galaxy Encounters
Tatum M. Umiamaka, Joshua E. Barnes
Spherical galaxy models with radially anisotropic velocity distributions merge faster than their isotropic counterparts. Here we investigate the effects of radially anisotropic hal…
Orbit decay in encounters between anisotropic spherical galaxies of equal mass
Lucas Saleh, Joshua E. Barnes
We investigate the effect of radial anisotropy on the rate of orbit decay in parabolic encounters of identical spherical galaxies. Our galaxy models have Hernquist density profiles…
A simple algorithm for orbit classification
Eliza E. Fulton, Joshua E. Barnes
We describe a simple algorithm for classifying orbits into orbit families. This algorithm works by finding patterns in the sign changes of the principal coordinates. Orbits in the…
