Complex systems in cosmology: "the Antennae" case study

Abstract

Due to its particular shape, "The Antennae" is a well-known complex cosmological dynamical structure. Classical simulations of this phenomenon are based on "top-down" models that required thousands of point-mass particles. We describe an approach for cosmological simulation, based on a hierarchical multi-agent system, and evidence is shown that this approach significantly reduces the number of elements needed to simulate "The Antennae" structure. © 2009 ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.
