Tailoring triaxial N-body models via a novel made-to-measure method

Astrophysics of Galaxies 2011-05-06 v1 Cosmology and Nongalactic Astrophysics

Abstract

The made-to-measure N-body method (Syer & Tremaine 1996) slowly adapts the particle weights of an N-body model, whilst integrating the trajectories in an assumed static potential, until some constraints are satisfied, such as optimal fits to observational data. I propose a novel technique for this adaption procedure, which overcomes several limitations and shortcomings of the original method. The capability of the new technique is demonstrated by generating realistic N-body equilibrium models for dark-matter haloes with prescribed density profile, triaxial shape, and slowly outwardly growing radial velocity anisotropy
